New All-In-One concept offers great setup versatility to find the best configuration for any track condition. When grip is low, the mid motor position shifts weight to the rear tires for increased rear traction and stability. When track conditions improve and grip is up, the front motor position lowers CG and moves weight forward for increased steering and better corner speed.
The XB2D lets the user choose the perfect configuration for their needs. The stand-up transmission of the mid motor configuration for lower traction, and the laydown transmission for higher grip conditions.
Gear Box Gears
Both idler gears are included to complete the transmission assemblies. A 36T graphite gear for the front motor build and a 25T graphite gear for the mid motor build. The 4 gear configuration is available only for the mid motor gear box.
The XB2D includes both motor plates for the front and mid motor gearbox configurations.
A graphite rear shock tower for front motor and composite tower for mid motor are included in each XB2D.
Both are specially design to have maximum performance for each gearbox.
Roll Center Holder
Roll center holders for both front and mid motor position configurations are included.
Changing transmission configurations also allows moving the electronics to alter weight distribution. Both battery straps are included to keep the pack secured in all situations.
Spur Gear Covers
Both gear covers are included for safety and to protect the transmission gears from debris.
The new XB2D chassis was shortened to increase grip on lower traction surfaces. The chassis is machined from 2.5mm Swiss 7075 T6 aluminum. The precision milling allows the chassis to create the desired flex and rigidity characteristics without sacrificing strength, while also reducing the vehicle weight. The chassis is then coated at XRAY’s own in-house robotic coating line.
The redesigned XB2 ball differential offers improved performance, durability, and easier maintenance. The externally-adjustable ball differential is machined from HUDY Spring Steel™ and is additionally hardened for extra durability and long lifespan. A high-quality carbide thrust bearing and carbide balls are included for ultra-smooth operation. Includes outdrive adapters designed for use with drive shafts with 2.5mm pin.
All new 2-pad slipper assembly offers smoother engagement for improved traction during acceleration. The stronger spring improves the consistency and ease of adjustment. An optional slipper eliminator is available to reduce rotating mass for improved throttle response in stock class racing when the slipper is not needed for traction assistance.
Multi-Adjustable Rear Suspension
All-new rear suspension features the new adjustable rear upright design, longer CVD drive shafts, and longer rear camber link. The new system offers a huge range of roll center tuning adjustments for different track conditions.
All-new rear uprights feature multiple set-up options for upper & lower roll centers. 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 axis of the connecting joint of the drive shaft to help generate more traction and increase stability.
There are three different uprights available: hard (included), graphite (optional), and aluminum (optional), each suitable for particular track conditions.
To accommodate the new, fully-adjustable rear uprights and ball differential, the drive shaft length is increased to 75mm.
The XB2 driveshafts are manufactured from world-renowned HUDY Spring Steel™ and feature 2.5mm drive pins for maximum drivetrain efficiency. The drive shafts are some of the world‘s 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.
With the multiple roll center adjustment possibilities, the rear turnbuckle is longer to accommodate all the different camber link position alternatives.
As a part of the Multi-Flex™ system, the front upper deck is used to adjust chassis flex. There are two different upper decks available – medium (optional) and hard (included). The harder material makes the car more predictable and forgiving on the track.
The XB2D now includes the Hard front lower chassis brace for improved handling and consistency.
Side Guard Brace
To improve front chassis flex, the front composite chassis braces were redesigned and shortened to allow for mounting all-new graphite side guard braces for better stability and performance.
Integrated Suspension Settings
The updated RR suspension holder fits both the new longer rear arms and standard arms for maximum tuning options.
The aluminum suspension holders feature Integrated Suspension Settings (I.S.S.™) which allows for quick & easy suspension geometry set-up.
Changing the position and shape of the included eccentric suspension bushings in the suspension holders, and adjusting the roll center shims and turnbuckle lengths, the XB2 suspension geometry is completely adjustable.
The all-new longer, rear arms update the rear geometry for better consistency and improved handling.
There are two different rear suspension arms available: hard (included) and graphite (optional), each suitable for particular track conditions.
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 three different caster blocks available – medium (option), hard (included) and graphite (option) – which are suitable for various track conditions.
The tiny yet tough steering blocks are comprised of composite steering blocks and graphite Ackermann extensions for variable Ackermann positions.
The composite blocks are molded from a special composite mixture for maximum strength.
There are three different steering blocks available – medium (option), hard (included) and graphite (option) – which are suitable for various track conditions.
To improve the precision of the shock shaft movement, the front composite shim was redesigned and updated with a more accurate mould design.
Well-built, reliable shock absorbers are extremely important for super-smooth suspension action on any type of track. The shocks on the XB2 have been specifically designed to be built easily, perform consistently, and last reliably. Careful attention was paid to the smallest details during the design process, as well as during long-term testing in various conditions.
Downstop is adjusted using composite shims under the pistons. Upstop travel is adjusted using composite shims under the shock collar.
Shock rods are machined from special steel material, precision hand-ground for maximum smooth operation, and additionally hardened for improved lifespan.
The XB2D comes equipped with offset hexes to perfectly match the width of the car with the new suspension arms and hubs.
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.
To adjust track-width, optional offset wheel hex drive hubs are available.
The included XB2 wheels feature a new, redesigned countersunk center area to allow the wheel nut to be positioned further into the wheel.
The wheels are perfect for high-competition racing. The wheels are made from a very flexible material, while still being ultra-durable to withstand impacts. The side of the wheel is aerodynamic for maximum performance. The wheels were designed to provide maximum traction.
Internal reinforcement ribs make the wheels as stable as possible and eliminate deformation. The wheels feature a 12mm internal hex.
The new high-performance Alpha 2 body was designed to increase downforce. This body generates 50% more grip then previous versions, which improves handling on low traction. The body is made from high-quality premium Lexan™ material.
The optional Beta 2 body is available for situations when less downforce is needed.
The stylish and effective rear wing was designed to have maximum rear grip on low grip tracks, and work perfectly with the XRAY XB2 body. Made from strong Lexan™ material, the wing is secured by the extended surfaces of the wing mounts and wing buttons to better support and extend the life of the wing.
Optional front Lexan™ wing (#323512) is used to generate front downforce and is mounted directly on the front.
The XB2D features greased ball-bearings for front steering blocks & rear uprights to increase lifespan in dusty conditions. The remaining bearings are degreased and oiled with AeroShell® Fluid 12 for maximum smoothness and long life.
A full set of 22 high-speed ball-bearings are used throughout the drivetrain to ensure maximum efficiency.
