Chassis.

The new composite chassis frame has a split design with a separate front part and rear chassis plate. The split design allows the entire rear suspension to be mounted in either standard position using the rear chassis plate, or to be placed lower by mounting the rear suspension directly to the aluminum chassis. The direct mounting of the rear suspension increases traction and is recommended for low-traction tracks.
Mounting the rear suspension directly to the chassis requires optional rear suspension holders 363311 & 363321. The split chassis is compatible with both XB4 & XB4 2WD.

The rear of the chassis features positions for additional optional weights which allow for quick and easy weight balance adjustment.

Suspension Arms.

All-new arms feature the innovative SFA™ (Suspension Flex Adjustment). Whether you are racing in low- or high-traction track conditions, you can easily adjust the flex of the arms by quickly and easily adding optional graphite stiffeners which change the stiffness of the suspension. The new arms include 4 holes where the optional graphite stiffeners are mounted, and the areas around the holes are strengthened for maximum durability.

SFA™ Graphite Stiffeners.

All-new innovative and unique SFA™ graphite stiffeners allow for super-quick suspension flex adjustment to easily adjust the traction of the car in various track conditions.

Whether you drive in low- or high-traction conditions, with the smart graphite stiffeners you can very quickly and easily adjust your car to suit current conditions. At the beginning of a race event when traction is low, the arms are used without the SFA™ graphite stiffeners. As traction increases, the suspension can easily be made stiffer by mounting the SFA™ graphite stiffeners for more stability and easier driving characteristics. The graphite stiffeners give the car maximum stability in chicanes and allow for easier and smoother steering.
Made from 1.6mm thick high-quality CNC-machined graphite material, the stiffeners can be easily mounted or removed by only a few screws.

The stiffeners are available only as an optional part.

Wheelbase Adjustment.

All-new suspension arms are narrower which allows for quick and easy wheelbase adjustment. Using included 2mm shims, both front and rear suspension arms can be moved either forward or rearward to adjust weight balance depending on track conditions. By moving the arms to the front, the balance and weight of the car are transferred more to the rear; this is recommendedfor medium– and high-traction conditions. By moving the arms to the rear, the balance and weight of the car are transferred more to the front; this is recommended for medium- and low-traction conditions.

The wheelbase shims allow not only to move the suspension forward/rearward, but also allows the wheelbase to be adjusted shorter or longer for fine set-up tuning under various track conditions.

Variable Shock Mounting.

The new design of the rear suspension arm allows very practical variable position of the rear shock absorbers. Depending on track conditions, the rear shock absorbers can be installed either in front or behind the shock tower.

Slipper Clutch.

The power from the motor is transferred to the drivetrain via an adjustable central slipper clutch for quick and easy tuning.

The new lightweight slipper clutch plates have a machined relief which decreased the friction surface which assists with clutch slip adjustment. With the new plates the pressure of the plate is on the circumference of the clutch pads, which increases the efficiency.

The new slipper clutch pads are produced from new ultra-efficient SLS material with very high slip efficiency and allows very precise adjustment of the slipper clutch.

The new clutch spring is much stronger which helps improve consistency and gives ultra-fine slipper clutch adjustment.
The clutch outdrives are super lightweight and manufactured from HUDY Spring Steel™ and are additionally hardened for extra life and reliability. The slipper plates are machined from premium Swiss 7075 T6 and additionally hardened and with a black final surface treatment.

Off-set Wheels.

The new front wheels feature +1mm offset which makes the front of the car wider and as such more stable.

Bulkheads.

Front & rear bulkheads were reinforced to withstand rigorous impacts and abusive racing conditions. The diameter of the holes for ball-bearings was refined to minimize ball-bearing play which results in increased lifetime of the gear’s teeth and minimizes the gears stripping.

Shock Towers.

Front & rear shock towers were redesigned and reinforced.

Machined from premium-grade 3.0mm graphite, the shock towers are lightweight and strong and have multiple shock positions as well as multiple roll center adjustment positions. The rear shock tower holds the wing mount.

Diff Outdrives.

Both front & rear differentials feature new reinforced diff outdrives to increase reliability.

Diff Bevel Gears.

To increase lifespan and reliability, both front & rear differentials include new reinforced diff bevel gears.

Ball Joints.

All feedback was considered and evaluated, and even the smallest details such as ball joints were refined and improved. To increase reliability, the ball joints were redesigned and reinforced.

Top Deck.

To new top deck was reinforced for increased reliability and other small details were improved for a more precise fit.

The top deck is machined from high-grade graphite, and its main design purpose is not only to hold the body mount but also to reinforce the chassis assembly by connecting the front diff bulkhead with the central drive system. The top deck captures the central drivetrain bearings and holds them in place in their supporting bulkheads.

Shock O-rings.

To improve shock sealing, the upper cap O-rings are included in the shock absorbers.

Shock Tower Protector.

In addition to the new front shock tower reinforced design, the XB4 includes an additional shock tower protector which can be used at extremely abusive tracks.

Ball Differential.

The optional ball differential was designed and is suggested for low traction track conditions. Externally adjustable ball differential is machined from HUDY Spring Steel™ and additionally hardened for extra durability and long lifetime. High-quality carbide thrustbearing is included for smooth operation and the carbide balls ensure ultra-smooth running. The ball differential comes factory pre-assembled..
"To create an all new platform in a new class is the most demanding and difficult task for an RC car designer. The benefit is that since you are starting from zero there are no limitations other than your imagination.

To design and develop this buggy was an incredibly challenging project. Nearly 2 years were spent in prototyping and development and the XRAY factory off-road team has tested many different designs and configurations ranging from conservative to crazy.

I am very happy and very proud to present you the final design chosen after extensive testing around the world in various conditions by some of the world's best drivers and backed-up with the artistic craftsmanship of our in-house XRAY factory production specialists. Designed, developed and fully manufactured in Slovakia, Europe, with XRAY's legendary attention to the details, fine materials and extreme performance, I am excited to present you the all-new XB4."

Dipl. Eng. Juraj Hudy XRAY XB4 designer

Concept.

The XB4 is a typical XRAY car – a premium, professional, high competition model racing car for the most demanding racers, developed and designed with attention to the smallest details. Manufactured from premium European materials, machined using state of the art Swiss and German machines and backed by premium service & support, the XB4 is a typical XRAY, a luxury masterpiece.

XRAY off-road platform.

The XRAY off-road racing cars have received honours and accolades all around the world, including multiple ‘Car of the Year’ awards from RC car magazines around the world as voted on by consumers, and countless victories at all levels of racing, including multiple National and

European Championship titles.

Over the decade the XRAY off-road cars set a new rise for premium quality and unbeatable reliability and have gained the hearts of racers around the world. The XB4 brings over the same characteristics from the large 1/8 off-road cars.
  • Functionality
  • Highest quality
  • Highest performance
  • Strength and durability
  • Premium materials
  • Easy to service
  • Easy to set-up
  • Long wearing
  • Ingenuity
  • Smart design

Multi-Flex™.

The invention of the XRAY Multi-Flex Technology™ has resulted in some of the most significant milestones in RC model car development in the last decade. This innovation, has not only resulted in awards and accolades, but has proven to be a distinct competitive advantage at tracks worldwide, helping XRAY cars dominate races at the local and national levels.
The XB4 is the world’s first 1/10 off-road chassis incorporating the Multi-Flex™ adjustment technology, which allows tuning the chassis flex for different track conditions.

It doesn’t matter if the track is low traction, medium or super high traction, you can adjust the chassis flex to suit the track conditions in a matter of seconds, and again adjust the flex easily when the conditions change. It has never been so easy to professionally set-up the flex. It is yet another smart innovation from XRAY.

SOFT

Use soft setting for low-traction, dusty tracks. The car will create a lot of traction with this setting but will have less steering and response compared to stiffer setting.

MEDIUM

Use medium setting for medium-traction tracks. This setting offers good balance between steering responsiveness and traction.

STIFF

Use stiff setting for high-traction tracks where a lot of steering and car response is required.

The more screws used, stiffer the car is and less screws used, softer the car is. Do not remove any other screw except those shown.

Chassis concept.

The revolutionary and unique chassis design of the XB4 features XRAY Multi-Flex™ technology. The Swiss 7075 T6 aluminum backbone and composite chassis-plate are firmly mounted together to create a solid framework with each piece playing a distinctive role:

Provides the car with stability and stiffness, while allowing torsional flex along the lengthwise axis.
Absorbs vibrations and works as the main Multi-Flex™ element, allowing the changing of flex independently in the front and rear of the car.

Aluminum chassis.

CNC-machined from high-quality Swiss 2mm 7075 T6 aluminum, the backbone is strategically machined in low-stress areas to make it as light as possible without affecting strength or rigidity.

The strong aluminum backbone protects the bottom of the car from extreme conditions and abusive jumps. The aluminum backbone is perfectly fitted to the composite chassis frame and all holes are perfectly countersunk to provide a smooth surface.

Composite Chassis Frame.

The precision engineered and designed composite chassis frame not only enables quick and easy Multi-Flex™ settings, but also houses the main components of the car. The front, center and rear drivetrain bulkheads are keyed into this frame, while it also provides locations for all of the required electronics.

The chassis tray design features reinforcement braces in both lengthwise as well lateral directions. The tray design ensures perfect protection from bottom and sides without requiring additional components.

Chassis weight balance.

The layout of the electronics placement was designed with the attention to the optimum weight distribution and weight balance. During the design and prototyping phase several different layouts were tested and an extensive amount of data was collected, compared and evaluated by the factory team before the final design was chosen.

The motor mount is oriented in the front on the right side, with servo, ESC and receiver placed on the opposite side for balance. To maximize balance both L/R and F/R, a saddle pack battery configuration was used, with the batteries placed to the rear between the spur gear and the suspension mounts.

Electronics layout.

All the electronics can be comfortably placed within the composite chassis frame. The servo mount is held to the chassis using 2 screws for easy and fast exchange. There is plenty of space behind the servo for the ESC and receiver placement.

Space has been reserved in front of the motor to allow for an additional cooling fan.

The wires between the motor and electronics are routed via a channel in the center of chassis which ensures that they will not interfere with the drive shafts or any other rotating parts. The chassis also features clips for the routing of battery wires.

Motor Mount.

The motor mount is another smart and innovative solution from XRAY. The motor is connected to an eccentric mounting plate, with the assembly then inserted into an integrated motor holder/drivetrain support. The design of this system allows quick and easy motor rotation to adjust gear mesh, and yet clamp securely using only a single screw.

To ensure that the motor will not come loose in a serious crash or if the motor mount is not tightened sufficiently, the motor plate has a bayonet mounting system which prevents it from being dislodged from the motor holder. By rotating the motor mount plate to the opposite direction, the motor can be quickly removed from the motor holder.

Removing the motor or adjusting the gear mesh has never been more comfortable or faster with changes possible in just a few seconds.

Drive Train.

The XB4 is conventional shaft driven 4WD off-road car featuring:
  • Front & rear gear differential with adjustable oil viscosity
  • featuring 35T crown gear and 14T pinion gear
  • Central slip adjustable clutch with main spur gear 81T
  • Front, central and rear CVD drive shafts
  • The internal ratio of the drive train is 1:2.5

Drive Shafts.

XB4 constant velocity drives (CVDs) are manufactured from world-renowned HUDY Spring Steel™. The drive shafts are some of the world‘s thinnest yet most durable drive shafts used in electric off-road cars.

Hardened with a proprietary hardening process, the drive shafts provide unbeatable lifetime and reliability.

The CVD assembly also feature a composite safety collar which ensures that the mounting pin will never fall out.

Diff Bulkheads.

XRAY’s genuine attention to the smallest details, R&D and engineering are obvious in the design of the diff bulkheads. Unique bulkheads allow super fast and ultra comfortable diff exchange and servicing by dismounting only 4 screws from the front of the bulkhead and from the bottom of the chassis. This super fast diff access is available both in the front and rear.

Gear Differential.

The XB4 gear diff ensures increased on-power steering which is needed on nearly all types of tracks, and is ideal for both carpet and clay tracks.

The super-smooth gear diff includes a composite case and cover with integrated crown gear. The internal gears are precision-molded from tough XRAY developed and mixed composite material ensuring high life time and super-smooth and efficient operation.

The maintenance-free diff design is a feature that will benefit racers of all levels. When the diff is correctly built, there is no need for maintenance for a very long time… no need for frequent oil changes, and no leakage due to our superior sealing system.

Diff Outdrives.

To reduce rotating weight, the super-lightweight diff outdrives are machined from HUDY Spring Steel™ material which allows us to additionally remove material on the outer part of the outdrives, further reducing the weight without effecting durability. The inner part of the outdrives are additionally hand-ground for maximum perfection and fitment into the diff case.

The outdrives are hardened using XRAY’s own special hardening process to provide extended life time and reliability.

Spur Gear.

Precision-molded spur gears are made from XRAY's exclusive secret blend of composite material, allowing the gear to run yet be robust enough to handle high performance brushless motors. The spur gears are designed to have the lowest possible weight while staying strong and light. Each gear is stamped with the tooth number for easy identification.

The XB4 comes equipped with 81T spur gear which suits majority of tracks. For additional tuning an optional 84T spur gear is available.

Suspension Concept.

The correct suspension geometry is one of the most important features of any RC model car yet at the same time is also one of the most difficult and challenging features for a designer.

The suspension is always a mixture of:
  • Design and shape of the individual suspension parts
  • Flex and hardness
  • Materials used
  • Mounting system
  • Geometry and position of mounting points of connecting parts

From the suspension arms, through the suspension blocks, to the light, yet robust steering blocks, every suspension part has been specially designed for 1/10 off-road racing platform to provide responsive racing characteristics in all racing conditions.

Over the years XRAY has successfully gained and utilized extensive knowledge of suspension geometry and stiffness, which has been applied while designing the suspension parts. The ultra-lightweight suspension parts are molded from a special composite material that makes the parts very light yet very durable to withstand the rigors of high-performance racing.

The XB4 platform features suspension parts inspired by the big brother XB9, yet re-engineered for the smaller 1/10 platform. The front and rear arms feature double shock mounting positions and integrated anti-roll bar mount.

I.S.S.™ Suspension Holders.

The aluminum suspension holders feature Integrated Suspension Settings (I.S.S.) which allows for super fast, easy and comfortable suspension geometry setting. This XRAY concept was first introduced in the very first XB8 and now has been carried over to the 1/10 scale XB4.

Using eccentric suspension bushings, which are inserted into aluminum suspension blocks, as well with the additional use of suspension shims, the XB4 suspension geometry can be completely adjusted including:
  • Caster
  • Camber
  • Front & rear Toe-in
  • Front & rear Roll-center
  • Front Kick-up
  • Rear Anti-squat
  • Wheelbase
  • Track-width

A complete set of various eccentric bushings is included for complete suspension geometry adjustment. The bushings are inserted into aluminum holders which are machined from premium Swiss 7075 T6.

Suspension Arms.

Suspension arms are one of the most important parts of any RC model car, as they directly influence the handling and racing characteristics of the car. The XB4 suspension arms are the result of long-term tests of different designs and layouts. Length, thickness, flexibility, geometry of suspension points and materials used… these are all the concepts and details that had to be thoroughly reviewed to create the optimum suspension arms.

The exclusive composite mixture used for suspension arms is a perfect balance between reliability and performance. The suspension arm itself is rigid enough to provide a responsive feel, yet soft enough to provide extreme durability.

Caster Blocks.

The 1-piece caster blocks are very lightweight yet the construction of the caster blocks makes them very stiff and rigid. The non-adjustable caster angle is preset for 9°. The roll center position can be easily and quickly adjusted by inserting different thickness of shims on the top of the caster block between the block and the vertical ball stud.

The caster blocks feature large openings for quicker & easier assembly/disassembly of the CVDs. The entire CVD assembly can be easily inserted/removed through the C-hub without the need for disassembly. The large openings also prevent collision of the CVD with the C-hub in serious crashes.

The front of the chassis is pre-angled with an integrated kick-up that influences caster angle, however, the position of the adjustable eccentric bushings in the I.S.S. suspension holders influence the caster as well. Therefore, if the eccentric bushings have roll center in middle position the caster angle is 9° and with the 9° in caster block the overall caster angle is 18° caster.

The total adjustable caster range in the kit is 16°~20°.

Optional caster blocks with 6° caster angles are available for further suspension geometry adjustment.

Steering Blocks.

The tiny yet tough steering blocks are molded from a special composite mixture for maximum strength.

Composite steering block inserts allow for very fast and comfortable lower roll center adjustment. With additional shims and extra inserts a fine tuning of roll center can be easily achieved.

For maximum drive train reliability larger 5x12 ball-bearings are used in the outer position with increased dynamic load. On the inner position the smaller 5x10 ball-bearings are used to minimize unsprung weight.

Lower Roll Center

When the longer bushing is used at the top, the roll-center is in lower position. Recommended for rough track to gain stability.

Higher Roll Center

When the longer bushing is used at the bottom, the roll center is in higher position. Recommended for smooth track to gain more steering.

Rear Uprights.

The very compact rear uprights are small in size but thanks to the special composite mixture used also very strong.

The lower roll center adjustment has 2 different positions on the upright and the upper roll center adjustment has 3 different positions. The rear uprights feature 0° toe to ensure stability and prevent suspension geometry changes in hard crashes.

For maximum drive train reliability larger 5x12 ball-bearings are used in the outer position with increased dynamic load. On the inner position the smaller 5x10 ball-bearings are used to minimize unsprung weight.

The outer suspension pin on which the rear upright sits features shims which allow for additional wheelbase adjustment.

Clamping Alu Hex Hubs.

Ultra-lightweight 14mm wheel hex drive hubs are CNC-machined from Swiss 7075 T6 black-coated aluminum. These ultra-true hex hubs have clamping design which ensures ultra solid mounting of the wheel on the hub.

The alu hex hubs are specially machined to reduce rotating weight while guaranteeing wobble-free wheel mounting.

To adjust the track width optional offsets are available -0.75mm and +0.75mm.

Dual Arm Steering System.

The dual arm steering system is very simple yet effective and features an integrated easily adjustable servo saver.

Ackermann is easily adjusted by quickly and easily changing steering link mounting positions on the steering plate.

Bump steer is easily adjusted for more aggression by inserting a shim between the steering block and steering linkage.

HUDY Spring Steel™ Turnbuckles.

To guarantee maximum reliability all turnbuckles are manufactured from special HUDY Spring Steel™ material for turnbuckles with a tougher core. These turnbuckles are used for front and rear upright linkages, steering system as well as for the servo saver.

Body Posts.

Beefy 6mm thick body posts are made from special composite material that provides maximum strength. The body supports are rounded to have a better fit and provide better support to the car body.

Battery Holders.

To change the batteries is easy and fast. The composite battery straps hold a saddle pack in the chassis and using two clips the battery pack can be easily removed.

Big Bore Shocks.

Well built and reliable shock absorbers are extremely important for super smooth suspension on every type of track. The shocks on the XB4 have been specifically designed to build easily, perform consistently, and last reliably. Attention was paid to even the smallest details during the design process, as well as during the long term testing in various conditions and track types.

The big bore shocks are membrane free, but still allow for easy, consistent build and rebound setting using the bleed-screw shock cap design.

The up-stop travel of shock rod is adjusted via rubber o-rings while the downstop is adjusted using composite shims under the pistons.

The aluminum body, lower nut as well bleeder shock caps are all machined from premium

Swiss 7075 T6 for maximum strength and hard black coated.

The pistons are made from Delrin and are molded using super precise moulds. There are several types of pistons included with different holes and diameters for precise shock adjustments. For custom adjustment even a set of blank pistons are also included.

The shock rods are machined from special steel material, precision hand-ground for maximum smooth operation and additionally hardened for increased lifetime.

Shock Springs.

The XB4 springs have been specifically designed to complement the big bore shocks.

The springs, like all the other XRAY springs, are manually measured, selected and matched into pairs to guarantee precisely equal length and damping characteristics.

There are two types of springs in offer:
  • The spring rate is constant during the entire spring compression. There are springs with different spring rates available as optional tuning parts.
  • The main advantage and benefit of progressive springs is that as the car initially enters the corner they work like a softer spring to provide maximum traction. At the same time, when the chassis begins to roll, in the middle of the corner, the spring rate progressively increases until it works like a stiffer spring which allows the car to maintain maximum cornering speed.

Silicone Oils.

XRAY Premium Silicone Oils are manufactured in Europe by a specialized premium silicone oil manufacturer; these new oils were exclusively created for XRAY. Each batch of premium oil is laboratory tested and calibrated to ensure the highest possible consistency and quality batch-to-batch. Based on the industry-standard cSt rating, the new line of oils will be easy to identify, adjust, and feel.

When following any setup sheets by XRAY or XRAY team drivers, you can be sure that the oils you will get for your car will be exactly same as used by the factory racing team, thus ensuring very exacting setups and handling of the car.

Anti-roll Bars.

Anti-roll bars are manufactured from special spring steel material and are included to stabilize the car at both front and rear. The roll bars are easily mounted to the diff cases and can be adjusted through the adjustable linkages.

Both front and rear anti-roll bars are interchangeable as they have same design and shape. The thickness of each anti-roll bar is laser engraved for easy identification. Anti-roll bar wires of different thickness are optionally available for fine-tuning.

Ball-bearings.

A full set of 22 high-speed, blue-sealed ball-bearings are used throughout the drivetrain to ensure maximum efficiency. All of the bearings are degreased and oiled with Aero Shell® Fluid 12 for maximum smoothness and long life.

Rear Wing.

Stylish and effective rear wing was designed to work perfectly with the original XRAY XB4 body. Made from strong Lexan material the wing is mounted to the wing mounts supported by extra flat shims to better support and extend the life of the wing.

Body.

The high performance low profile aerodynamic body was designed by XRAY to perfectly fit the XB4 and to work in most track conditions effectively. The front and rear of the body have been designed to provide downforce for maximum stability of the car. The body sides as well the cockpit sides are as flat as possible to allow the air flow around the body for the side stability of the car. On the top of roof
two flow channels are incorporated for proper air flow. The body is made from high quality premium Lexan material.

Wheels.

Specially designed XB4 wheels are included in the kit and they do not only perfectly fit but they are also perfect for high competition racing. The wheels are made from very flexible material but are still durable against impacts.

The side of the wheel is aerodynamic for maximum performance.

The special features of the wheel are visible from the inside – the reinforcement ribs are designed to make the wheels as stable as possible and to eliminate deformation.

The wheel design features a 14mm internal hex.

Chassis Balance.

The chassis design focuses on balanced weight distribution and weight transfer. The chassis features pre-drilled holes for additional weights for optimum car balancing. Centerline holes are pre-drilled for easy balancing with the HUDY Chassis Balancing Tool #107880.

Adjustment Possibilities.

The extensive and impressive range of adjustment possibilities includes:
  • Caster
  • Camber
  • Toe
  • Kick-up
  • Anti-squat
  • Ride height
  • Downstops
  • Track-width
  • Lower roll center
  • Upper roll center
  • Roll center positions
  • Bump steer
