Gear Box.
Longer gear box – for front motor position - keeps more weight over the front axle for improved steering and corner speed on high grip surfaces. Included in the Carpet edition.
Gear Differential.
The gear differential has 35% larger internal oil volume than previous design to increase consistency of the diff action, yet at the same time it is significantly narrower to fit into the LCG gear box and to move the rotating weight closer to the centerline.
The super-smooth gear diff includes a composite case and cover with internal satellite gears that are precision-molded from special XRAY-developed graphite composite material, ensuring a long lifespan and super-smooth, efficient operation.
The gear differential is suggested for medium to high traction conditions as it increases on-power steering that is beneficial on all carpet tracks.
The gear differential is included in the Carpet edition.
Easy Diff Access.
Gear box features super easy access to the differential. Both gear boxes for Dirt and Carpet edition have the super easy diff access by removing only 6 screws.
Each gear box incorporates all the finest details and craftsmanship. All parts fit together perfectly, and the super-easy access to the rear differential will be appreciated by every racer. The durable gear box houses the differential with all the transmission components and serves as the mounting point for the rear roll center holder, motor plate, and rear shock tower.
Diff Height Adjustment.
The gear box features differential height adjustment. There are 6 height adjustment positions available using the included eccentric bushings. The ideal position will vary depending on the track conditions, ride height and the size of the tires used.
Slipper Clutch.
3-pad slipper – less slippage to generate more consistent braking at high traction conditions, included in Carpet edition
Rear Suspension Arms.
Carpet edition – supper narrow arms used from XB4 allows to move the arms more frontwards that moves the weight into the rear of the car.
Front Suspension Arms.
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 arm also features a mounting position for the optional front anti-roll bar.
There are two different front suspension arm hardness alternatives available: hard (included) and graphite (optional), each suitable for particular track conditions.
The front arms are universal for both Dirt and Carpet edition.
Fully Adaptive Steering System.
The XB2 steering system was redesigned for both high traction and low traction conditions. The Fully Adaptive Steering System has many new parts including the steering arms, steering plate, servo horns, steering linkage, and pivot balls. The same components are included in both Carpet & Dirt Editions but allow different build configurations to alter the geometry depending on the track’s conditions. Smart & easy.
Front Roll Center Holder.
The wider front roll center holder was updated with an additional outer position that is especially suited for high speed tracks where less front end dive is required.
The design of the roll center holder was also updated for mounting the optional front anti-roll bar directly on the holder.
The front roll center holder is universal for both Carpet and Dirt Editions.
Steering Blocks.
The Carpet Edition now features the new 3 slots steering block extensions better suited for high traction conditions. These extensions allow the wheels to turn more and provide more steering in corners. The overall travel was increased so the car has more steering in tight corners.
The Dirt Edition includes the 2 slots steering block extensions more suitable for lower traction conditions.
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
Anti-Roll Bars.
In specific track conditions when the front or rear of the car need more stabilization, an optional anti-roll bar (XRA322400 or XRA323400) can be easily installed. The anti-roll bar is mounted to the front/rear roll center holder and can be adjusted via the included linkages.
Anti-roll bar wires of different thicknesses are available for fine-tuning with the wire thickness laser-engraved on each bar for easy identification.
Shocks.
The front shock absorber bodies and shock shafts are longer by 2mm to maintain the correct down travel with the new tower. Combined with the new shock towers and suspension geometry, these changes increase steering and improve jump landing.
The big-bore shocks are membrane free, but still allow for easy, consistent building and rebound control using the bleed-screw shock cap design.
The aluminum body and lower cap are all machined from premium Swiss 7075 T6 aluminum.
The shock shafts are machined from special steel material, precision hand-ground for maximum smooth operation, and additionally hardened for an increased lifespan.
Battery Holder.
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 on the rear suspension.
The height of the battery backstop is also adjustable for different battery sizes.
The battery holder is mounted to the chassis through one connecting screw on each side brace to eliminate any negative effects on chassis flex.
The battery holder is universal for both Dirt and Carpet edition.
Side Guards.
Side guards integrate with the bent chassis and incorporate the adjustable battery holder system.
The tough composite side guards use double-sided Velcro™ tape to mount the body to the chassis and to seal against dirt.
The side guards are universal for both Dirt and Carpet edition.
Side Guard Braces.
Graphite side guard braces with redesigned shape make the front of the car more stable and more predictable. With the multiple mounting positions there are three flex settings available.
Soft setting – more aggressive front of the car
Medium setting – setting in between
Stiff setting - more precise handling of the car
The side guard braces are universal for both Dirt and Carpet edition.
Multiple Servo Position.
To allow for more precise weight balance adjustment, the servo position is adjustable either more rearwards or frontwards; there are 3 positions to choose from.
When the servo is moved rearwards, there is more weight on the rear and less weight on the front. This results in less diving into a corner, while increasing rear traction. Recommended for low- and medium-traction conditions.
When the servo is moved more frontwards, there is more weight on the front and less weight at the rear. This increases the diving effect but reduces rear traction. Recommended for high- and very-high traction conditions.
Arm Mount.
The lower composite arm mount is an important part of the chassis where the lower arms mount, and the block has an integrated 26° kick-up angle. Optional aluminum and brass arm mounts are available for further weight balance adjustment.
Caster Blocks.
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.
Drivetrain.
The XB2 is a conventional gear-driven 2WD off-road car featuring:
Rear Ball Differential (Dirt Edition) or Gear Differential (Carpet Edition) with adjustable oil viscosity, featuring 53T gear and internal satellite gears
25T (Dirt Edition) or 38T (Carpet Edition) graphite composite idle gear
20T super-lightweight Swiss 7075 T6 hardcoated aluminum top shaft
Adjustable slipper clutch with 78T main spur gear
Rear CVD drive shafts
Spur Gear.
Precision-molded spur gears are made from XRAY's exclusive secret blend of composite material, allowing the gear to run true 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 XB2 is equipped with an 81T spur gear which suits the majority of tracks. For additional tuning, optional 75T, 78T, and 84T spur gears are available.
High Traction Body.
The XB2C’21 and XB2D’21 each feature a new XRAY Gamma body specifically designed with super-smooth airflow and revised downforce characteristics fine-tuned for their intended conditions.
The carpet version of the all-new body, the Gamma 2C, is designed especially for high traction conditions and improves the stability in fast corners, chicanes and helps with rotation in tight corners.
The Gamma Carpet body is also available in lightweight version.
Wings.
The Carpet and Dirt Editions of the XB2 each feature a different wing paired to work with their particular body. Made from strong Lexan™ material, the wing is supported on the wing mounts by extended flat shims to better support and extend the life of the wing.
Various wing designs in different thickness are available separately to alter downforce and handling. The thicker wing gives higher traction and stability but gives reduced steering.
Wheels.
The included wheels are IFMAR standardized with the new wheel hex offset. The wheels feature a redesigned countersunk center area to allow the wheel nut to sit deeper in the wheel.
The wheels are perfect for high-competition racing. They feature internal reinforcement ribs to provide stability and resist deformation, yet they are made from a flexible material to provide durability and withstand impacts.
The side of the wheel is aerodynamic for maximum performance. The wheels were designed to provide maximum traction.
The wheels feature a 12mm internal hex.
Turnbuckles.
For maximum reliability, all turnbuckles are manufactured from special HUDY Spring Steel™ material for turnbuckles which features a tougher core. These turnbuckles are used for front & rear upright linkages and steering system.
Wheelbase & Weight Balance Adjustment.
Outer suspension pins holding the front caster block and rear uprights feature wheelbase shims for quick & easy wheelbase and weight balance adjustment. Using included shims in rear and in front, both front and rear blocks can be moved forward or rearward to adjust weight balance depending on track condition.
By moving the arms to the front, the balance & weight of the car are transferred more to the rear; this is recommended for medium- and high-traction conditions. By moving the arms to the rear, the balance & weight of the car are transferred more to the front.
