The all-new XB2 platform demonstrated its high-performance potential with its debut at the highly contested Florida Carpet Championship, where it took 2x TQ, Win and multiple podium finishes against the stiff competition from the world’s best drivers.

XRAY XB2 has been successful since its earliest versions released several years ago. From local clubs to international competitions, the XB2 has achieved success at all levels of racing including winning the ROAR Nationals.

Designed, developed, and fully manufactured in-house at the XRAY factory in Slovakia, Europe, using the most high-tech German and Swiss machines and premium European materials, crafted with XRAY's legendary attention to detail by our artistic production specialists. The XB2 is truly a masterpiece. 

The XB2 platform works at the highest competition level in any track conditions, whether it be super-low-traction dusty tracks, medium-traction, or super-high-traction carpet or astro turf; there is an XB2 for you that will handle flawlessly in any of these conditions.

There are two different XB2 kits to choose from – Carpet Edition and Dirt Edition, both built on the same platform with full compatibility with interchangeable parts.

The Carpet Edition is designed for medium to very-high traction conditions, while the Dirt Edition is designed for very-low to medium traction conditions.

The Uni-Platform™ allows either version of the XB2 to be tuned or converted to suit any track conditions with only a few additional parts.

Multi-Conditions Concept.
Each new XB2 kit includes the parts necessary to build and adjust the car for a wider range of track conditions compared to previous models. The Carpet & Dirt Editions are each equipped for their unique surface requirements; both including a versatile set of components to adapt the new XB2 to a wider variety of conditions right out of the box.

The front assembly receives significant improvements for 2024, featuring an all-new bridge style front upper deck, new steering system and servo horns, new shock tower with the shocks positioned behind the tower, new side braces and an improved play-eliminating anti-roll bar mounting system.

All-new XB2 one-piece chassis provides more consistent performance in all track conditions. The one-piece design eliminates use of the previous lower chassis brace, and new geometry from the integrated chassis kick-up reduces dive under braking and generates more corner speed.

Chassis flex was optimized to work from low traction to high traction conditions. The chassis is now slightly wider to fit the latest batteries and features milled areas and mounting holes for the optional balancing weights and cooling fan holder. 

CNC-machined from high-quality 2.5mm Swiss 7075 T6 aluminum, the lightweight chassis retains the necessary strength and rigidity, and is titanium color coated at XRAY’s own in-house fully robotic coating line.

There are different chassis length alternatives to tailor performance to particular track conditions. Both Carpet and Dirt versions come with specially selected chassis lengths.

The Carpet version includes the mid-length chassis that provides better stability and is suitable for higher traction conditions.

The Dirt version includes the short chassis to generate maximum traction and is suitable for low traction conditions.

The side braces were redesigned to support the one-piece chassis design and connect with the new front end. The elevated shape at the front of the new braces connects directly to the new bridge upper deck with less hardware. The flex of the side braces was optimized to improve front stability & more rear traction.  The braces feature additional mounting holes for the battery holders to expand the range of battery position choices.

The side braces are available in two different hardness alternatives. Both Dirt and Carpet edition comes with medium stiffness and optional hard braces are suggested for extra high traction conditions.

The tough composite side braces also work great for using double-sided Velcro™ tape to mount the body to the chassis and seal against dirt.

The redesigned side braces allow mounting the battery holders in an extra forward position to move the battery weight as far forward as possible. This additional weight balance alternative expands the weight balance adjustment range to help achieve the best performance on any track condition.

Tweak-free fully adjustable battery holder is integrated into the side guards allowing easy and fast battery position adjustments, as well as simple battery installation through the smart quick-release system.

The battery pack can be easily moved front/rear to adjust the balance of the car. When the rear motor brace is removed, the battery pack can be moved completely rearward to maximize the rear weight bias and generate extra traction through the rear suspension.

The height of the battery backstop is adjustable for different battery sizes.

The battery holder is mounted to the chassis through one connecting screw on each side brace to eliminate any effect on chassis flex. 

The battery holder is universal for both Dirt and Carpet edition.

All-new bridge style upper deck helps to optimize flex from side to side and front to rear while also providing clearance for the new steering system. The upper deck also accommodates the anti-roll bar collar for improved functionality and allows mounting the shock absorbers behind the shock tower for better protection in a crash.

Steering arms, Ackermann plate and the servo arm were reconfigured for more precise steering feel. Thanks to the upper deck design, the steering system also has more space to achieve the improved steering performance. To integrate with the one-piece chassis, the steering post was updated as well.

To improve the reliability and strength, the steering blocks are molded from a medium hardness composite mixture that is suitable for most track conditions. The new medium compound significantly improves the reliability to enable finishing a race after significant crashes or impacts.

Both Carpet and Dirt editions now feature new 2 dot steering block extensions better suited for all track conditions. These extensions create a more linear steering that improves control in all conditions.

There are three different steering blocks available – medium (included), hard (option) and graphite (option) – which can be used to fine tune steering response for various track conditions.

To improve the reliability and strength, the caster blocks are moulded from medium hardness composite mixture that is suitable for most track conditions. Just like the included steering blocks, the new medium compound significantly improves the reliability and ensures finish a race even after a punishing crash.

The caster blocks are very lightweight, yet their construction makes them very stiff & rigid. The caster can be adjusted with values 0°, 2.5° or 5° by using included caster bushings.

There are four different caster blocks available – medium (included), hard (option), graphite (option) and aluminum (option), each one suitable for different track conditions.

The redesigned front roll center holder features the two most widely used roll center positions that are suitable for all track conditions. The new roll center block connects to the one-piece chassis and bridge upper deck to form a strong front structure.

The new design of the roll center holder mounts the front anti-roll bar directly on the holder.

The front roll center holder is universal for both Carpet and Dirt Editions.

The updated arm mount is an important part of the suspension, connecting the lower arms to the chassis plate. The included composite mount has a 0° kick-up angle, resulting in overall kick-up matching the integrated chassis kick-up of 26°.

Optional aluminum and brass arm mounts are available for weight balance or kick-up adjustment. The aluminum arm mount also includes a provision for a 10g Tungsten Weight for additional weight balance choices.

The all-new big bore 13.2mm shocks parts are redesigned for overall handling and performance improvements. The big bore shocks improve landings and provide better control over surface unevenness and bumps to improve traction.

There are two different thickness pistons (2.0 and 2.5mm) included in the kit in pre-drilled and blank alternatives.

The super-efficient pre-oiled X-rings ensure smooth operation and prevent dust inside the shock assembly.

The XB2 shock absorbers feature eccentric lower mounting pivot ball that changes the angle of the shocks when mounted in the arm.

Shock extension is limited using composite shims under the pistons. Maximum compression is limited using composite shims under the shock collar.

The shock absorbers are universal for both Dirt and Carpet edition.

The new piston choices were updated for ideal fit and dampening in the new big bore shock bodies. All-new 2-hole pistons (1.6 and 1.8mm) are included in 2.0mm or 2.5mm thickness alternatives.

In addition, two sets of blank pistons in both thickness alternatives are included for individual custom modification.  All pistons are made from Delrin and are molded using ultra-high precision moulds.

A completely new range of conical springs are available for the new big bore shocks.

Carpet and Dirt edition include 2 complete sets of springs chosen for their intended track conditions.

The XB2 springs, like all other XRAY springs, are manually measured, selected, and matched into pairs to guarantee precisely equal length and damping characteristics.

Each spring is laser-engraved with stripes to clearly indicate its firmness.

Both front & rear shock towers compliment the new big bore shocks and suspension changes on the new XB2’24.

The extra strong front shock tower is mounted further forward and gives the needed clearance to install the shocks behind the tower for better protection in a crash.

A composite cover is included for the front tower to provide protection in crashes and increase lifespan.

The included front wing is mounted to the front shock tower.

Lowered shock mounting positions on the rear tower allow for a softer set-up to generate more traction but with less roll.

Front & rear shock towers are machined from premium-grade graphite that is lightweight & strong, with multiple shock and roll center adjustment positions.

The shock towers are universal for both Dirt and Carpet edition.

Rear Suspension Holders RF & RR use a wider pin placement and integrated 3° toe-in geometry for increased stability in all conditions.

The wider suspension holders provide more stability and give more support in and out of each corner.

The aluminum suspension holders feature Integrated Suspension Settings (I.S.S.™) which allows for quick & easy suspension geometry set-up.

Machined from premium Swiss 7075 T6 aluminum and black coated.

The suspension holders are universal for both Dirt and Carpet edition.

To improve the reliability and strength of the suspension arms, both front and rear arms are moulded from medium hardness composite mixture that is suitable for many track conditions. The new medium compound significantly improves the strength to avoid crash related failures that prevent finishing the race.

The design of the suspension arms allows for a sufficient range of adjustments and the opening for the C-hub is large for a wide range of wheelbase adjustments possibilities.

The shock mounting location is wide to allow use of the eccentric shock pivot ball to move the shock absorber between two different positions creating different shock angles that affect traction and corner speed. The arm also features a mounting position for the optional front anti-roll bar.

There are three different front suspension arm hardness alternatives available:  medium (included) hard (option) and graphite (optional), each beneficial in different track conditions.

As with the other suspension components, the front arms are molded from a new medium hardness composite mixture to improve reliability and strength. The medium composite provides excellent performance on a variety of conditions with the added benefits of increased strength to help finish the race.

Front suspension arms have a universal design for both Dirt and Carpet editions. The suspension arms have geometry for improved handling and the repositioned lower shock mount locations lower the shocks and shock tower to decrease the CG.

The design of the arm allows for a greater range of adjustments. The opening for the C-hub is larger for greater wheelbase adjustments possibilities compared to previous versions.

The shock mounting location is wider to allow use of the eccentric shock pivot ball to move the shock absorber between two different positions creating different shock angles that affect traction and corner speed.

The front arms are universal for both Dirt and Carpet edition.

New rear uprights feature updated lower roll center positions that improve stability of the car with less collapse in high-speed corners. There are now two different composite rear uprights with Lower & Higher Roll Center positions, and both are included in Carpet and Dirt editions for additional set-up adjustments.

To improve the reliability and strength, the uprights are moulded from medium hardness composite mixture that is suitable for most track conditions.

Rear uprights feature aluminum roll center mounts with multiple upper roll center positions.

The upper roll center is adjusted at the camber linkage via shims (up/down & in/out), while the lower roll center is adjustable via eccentric inserts for 9 different positions (up/down & in/out).

The multi-function uprights have the upper roll center position in the middle of the axis of the driveshaft joint to help generate more traction and increase stability.

There are four different uprights available: medium (included) hard (optional), graphite (optional), and aluminum (optional), each suitable for particular track conditions.

Both Rear Motor Gear Box and Forward Motor Gear Box are now included in each kit for configuring the car for best performance on many different track conditions.

Super-narrow, ultra-low CG gear boxes (LCG) features quick & easy diff access. The narrower design of the gear box reduces weight and moves all parts closer to the chassis centerline.

Forward Motor Gear Box – Longer - for forward motor position - keeps more weight over the front axles for improved steering and corner speed on high traction surfaces.

Rear Motor Gear Box – Shorter - for rear motor position - improves traction on low traction surfaces by moving the weight of the motor and top shaft closer to the rear axles.

The Gear diff in the Carpet edition was redesigned to allow for unified drive shafts length for the Ball Diff and Gear Diff alternatives. The diff case, diff cover and diff outdrives were updated.

The gear diff comes now with steel satellite gears for improved efficiency and increased lifespan.

The gear differential is suggested for medium to high traction conditions as it increases on-power steering and is beneficial on all carpet tracks.

The new universal 2-pad slipper was developed to work in all different track conditions and features shorter lightweight top shaft, slipper clutch plates with larger engagement area, larger clutch spring & slipper clutch nut.

The 2-pad slipper controls driveline slip more efficiently for better acceleration and improved on-throttle landing transitions.

The slipper pads are made from ultra-efficient SLS material with very-high slip efficiency, thus allowing very precise slip adjustment.

The lightweight slipper plates are machined from premium Swiss 7075 T6 and additionally hardened before a final black surface treatment. The plates have a machined relief which decreases the friction surface to assist with clutch slip adjustment. With this plate design, pressure is focused on the circumference of the clutch pads for increased efficiency.

Front & rear anti-roll bars were redesigned to match the new chassis layout and improve performance. The front bars’ center sections are narrower to match the one-piece chassis design. The anti-roll bars are used especially for high traction conditions and are included in Carpet edition.

The rear anti-roll bar features easy height adjustment from the top of the ball joint to balance left and right fitment and to ensure the wire will not contact the drive shaft.

Anti-roll bar wires of different thicknesses are available for fine-tuning with the wire thickness laser-engraved on each bar for easy identification.

To simplify the spare parts compatibility, the required drive shafts length is unified between the Gear Diff and Ball Diff. Thanks to the new gear diff design, the 77mm long drive shafts now fit both differentials.

Manufactured from world-renowned HUDY Spring Steel™ the drive shafts feature 2.5mm drive pins for maximum drivetrain efficiency. The drive shafts are some of the thinnest yet most durable drive shafts used in electric off-road cars. Treated with a proprietary hardening process, the drive shafts provide unbeatable lifespan and reliability.

To unify the wheel hubs in the Carpet & Dirt Edition, both include the same wheel hubs with 0mm offset in front and +2.25mm offset in rear.

Ultra-lightweight 12mm wheel hex drive hubs are CNC-machined from Swiss 7075 T6 black-coated aluminum. These ultra-true hex hubs have a clamping design which ensures ultra- solid mounting of the wheel on the hub.

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