Multi-Adjustable Rear Suspension.
All-new redesigned adjustable rear suspension features the new rear upright, unique multi-length adjustable CVD drive shafts, and longer camber link. This new system creates a huge variety of roll center adjustments for different track conditions. Changing roll center has never been quicker or easier.
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 upright configuration, the all-new drive shafts are longer. Featuring XRAY’s own unique multi-length drive shaft adjustment there are 4 different length-adjustable positions to alter the length of the drive shaft depending on the roll center position. The all-new safety collar eliminates the clearance of the drive shaft and prevents the drive pin from getting loose.
XB2 constant velocity drives (CVDs) 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. Hardened with a proprietary hardening process, the drive shafts provide unbeatable lifespan and reliability.
Rear Drive Axles.
Unique drive shaft length adjustment uses 4 different connecting hole positions at the drive axle end to allow changes to overall driveshaft length. Another great XRAY innovation that accommodates different roll center positions without needing to use drive shafts of differing lengths.
With the all-new multiple roll center adjustment possibilities, the rear camber link is longer to accommodate all the different roll center position alternatives.
The XB2 now includes the popular hard suspension blocks and 1-slot steering block extensions to improve steering characteristics.
The tiny-yet-tough steering blocks are comprised of composite steering blocks and graphite extensions for variable Ackermann positions.
There are three different steering blocks available – medium (optional), hard (included), and graphite (optional), each suitable for particular track conditions.
The SLP (Super Low Profile) shock towers reduce front roll to allow running the car without front anti-roll bar and allowing the use of more droop for better landings. The lowered shock towers improve the handling of the XB2, especially in high-traction conditions.
CNC-machined shock towers are made from 4.0mm thick premium-grade graphite material for incredible strength and long lifespan. Includes multiple shock positions.
All-new SLP (Super Low Profile) shock absorbers offer superior performance, especially for high-traction conditions where together with the SLP shock towers there is a reduced roll of the car, thus allowing the use of more droop for better landings. Both front shock bodies and shock rods were lowered.
The shocks are membrane-free while still allowing for easy, consistent building and rebound setting using a bleed-screw shock cap design.
Downstop is adjusted using composite shims under the pistons. Upstop travel is adjusted using composite shims under the shock collar.
The aluminum body, lower nut, and bleeder shock caps are all machined from premium Swiss 7075 T6 aluminum.
Shock rods are machined from special steel material, precision hand-ground for maximum smooth operation, and additionally hardened for improved lifespan.
SLP Shock Springs.
To accommodate the all-new SLP shock absorbers, a new series of SLP shock springs was created. While the new springs were designed specifically for the SLP shocks all of the previously available shock springs will fit the new XB2, providing a large range of tuning options.
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.
Spur Gear Cover.
All-new molded composite gear cover prevents contact of the spur gear with the body. Moulded from strong, lightweight material, the cover helps to protect the body shell and spur gear.
The included XB2 wheels feature a new, redesigned countersunk center area to allow the wheel nut to be sunk deeper.
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 XB2C includes all-new, completely redesigned, high-performance, low-profile Beta 2 body with super-smooth airflow and all-new downforce areas. The Beta 2 body helps the XB2 by increasing steering & stability while also improving handling in jumps.
The front part of the body has a new high-downforce area. The sides of the body have upper downforce areas to generate more mid-body downforce, and the straight sidewalls improve stability. The upper part of the body was redesigned with a smooth flow channel for stability.
Different XB2 bodies are available in different thicknesses for fine tuning the performance of the car.
The XB2C 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.
Adjustable Gear Box Height.
To increase performance in high-traction conditions, the XB2 can use super low ride height. To keep the drive shafts linear the gear box can be raised by 2mm using optional graphite plates. There are two different ride height adjustable plates which allows to raise either only the gear box or also the entire rear suspension.
At the heart of XRAY's philosophy is a firm commitment to perfection when it comes to engineering, design, performance and support, all made possible by state-of-the-art in-house manufacturing. The XB2 is the epitome of perfection that is typical for XRAY.
Dipl. Eng. Juraj Hudy
XRAY Chief Designer
After 3 years of extensive development and testing in all track conditions (including carpet, astro turf, and dirt) we have released one of the best-performing 2WD 1/10 off-road car. Since that day we have remain committed to our goal to improving our products by continuous development and testing to ensure that you always get the best-performing XB2 straight out of the box.
XRAY XB2 Designer
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 and 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 grip conditions.
The Uni-Platform™ allows either XB2 edition to be tuned or converted to suit any track conditions with only a few additional parts.
Chassis is machined from custom-produced 2.5mm Swiss 7075 T6 aluminum. The special design ensures that different areas of the chassis have the proper flex – either stiff or soft – to decrease the CG. The precision milling allows the chassis to be stiff enough to perform properly without risk of bending.
CNC-machined from high-quality 2.5mm Swiss 7075 T6 aluminum, the chassis is lightweight without affecting strength or rigidity, and is additionally black coated at XRAY’s own in-house fully robotic coating line.
Weight distribution, chassis width & length, and proper flex have all been incorporated into the design of the chassis.
Narrower suspension holders with new rear suspension geometry gives increased rear traction.
The aluminum suspension holders feature Integrated Suspension Settings (I.S.S.™) which allows for quick & easy suspension geometry set-up.
The invention of 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 to help XRAY cars dominate races at local and national levels.
The XB2 incorporates Multi-Flex™ adjustment technology, which allows tuning the chassis flex for different track conditions.
Regardless if the track has low, medium, or super-high traction, you can adjust the chassis flex to suit track conditions to gain a distinctive advantage.
The electronics layout allows for moving the batteries frontwards/rearwards, using standard or mid-size servos, using short pack or saddle pack batteries, and using different motor placement
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.
Side guards are an integral part of the XB2 Multi-Flex™ system. Moulded from medium-hardness composite material, the side guards make the chassis frame flex suitable for the majority of track conditions.
The tough composite side guards feature double-sided Velcro™ tape to seal the body perfectly to the chassis and seal against dirt.
There are two different chassis braces available – medium (included) and hard (optional) – which are suitable for particular track conditions.
The included side guards are moulded from medium-hardness composite and make the car faster in corners.
An optional hard-hardness composite moulded braces give the car increased stability on jumps.
The front lower chassis brace is another component of the Multi-Flex™ system that influences flex and handling. There are two different chassis braces available – medium (optional) and hard (included), each suitable for particular track conditions. The brace is mounted directly to the chassis to hold the entire front assembly and front suspension, including the front protection bumper.
An optional medium-hardness composite molded brace is suitable for low- and medium-traction tracks.
The included brace is moulded from hard-hardness composite and is suitable for high- and very-high-traction tracks.
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), each suitable for particular track conditions.
An optional medium-hardness composite moulded upper deck is suitable for low- and medium-traction tracks.
The included upper deck is moulded from hard-hardness composite, and is suitable for high- and very-high-traction tracks.
Graphite 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.
The gear box has an updated, narrower design to accommodate the narrower suspension holders. Using the narrower suspension geometry, the XB2 generates more rear traction.
The lightweight, tiny gear box accommodates 3-gear configuration with right-side motor position.
The XB2 gear box is designed with all the finest details and craftsmanship incorporated. All parts fit perfectly together, 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 rear transmission, and allows the mounting of the rear roll center holder, motor plate, and rear shock tower.
Carpet Edition and Dirt Edition each have unique gear boxes specifically designed for different track conditions.
Gear Box Gears.
To generate maximum traction, steering, and high-speed stability, the gear box uses a 3-gear configuration. For some specific track conditions (such as large and open tracks) an optional 4-gear configuration gear box can be used.
Gear differential features diff outdrives designed for use with 2.5mm pin.
The strong diff outdrives are the result of a new hardening process that increases lifespan and reliability.
The XB2 rear gear differential is standard in the Carpet Edition, offering increased on-power steering that is beneficial on nearly all types of tracks but is especially great on carpet and astro turf.
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 long lifespan and super-smooth, efficient operation.
Dirt Edition only
The XB2 ball differential is standard in the Dirt Edition and is recommended for all XB2 configurations when used on very-low to medium-traction dirt and clay surfaces. 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 thrustbearing and carbide balls are included for ultra-smooth operation. The ball differential comes factory pre-assembled.
Easy Diff Access.
Access to the rear differential is super easy on both Carpet Edition and Dirt Edition. By just releasing a few screws on the rear cover of the gear box, the differential can be easily taken out and inserted back inside without the need for further disassembly. Smart engineering.
The XB2 is a conventional gear-driven 2WD off-road car featuring:
Rear ball differential (Dirt Edition) or gear differential (Carpet Edition)
Power from the motor is transferred to the drivetrain via an externally-adjustable central slipper clutch for quick & easy tuning. The 3-pad slipper clutch ensures super-smooth clutch operation and efficient and consistent braking. It is very easy to make ultra-fine adjustments to the clutch externally.
The slipper clutch 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.
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, 84T and 87T spur gears are available.
The black-coated Swiss 7075 T6 aluminum motor plate holds the slipper clutch assembly as well as the gear box, and features an adjustable motor plate position. To reinforce the assembly, the motor plate is connected to the upper brace mount via a motor plate brace.
Carpet Edition and Dirt Edition both have different Motor Plates, specifically designed for the particular track conditions.
Changing batteries is quick & easy with the included battery strap with aluminum nuts. The battery pack can be installed either frontwards or rearwards, and the included foam spacer helps to ensure the battery pack will not fall out. The chassis layout allows the use of either short packs or saddle-pack batteries.
There are two different battery straps available – composite (included) and adjustable graphite (optional), each suitable for particular track conditions.
The included composite battery is suitable for low-, medium- and high-traction tracks.
An optional adjustable graphite battery strap is suitable for very-high traction tracks and suggested especially for carpet racing.
Correct suspension geometry is one of the most important features of any RC model car, while at the same time being one of the most difficult & challenging features for a designer.
Suspension is always a mixture of
From the suspension arms, through the suspension blocks, to the light yet robust steering blocks, every suspension part has been carefully designed for the 2WD 1/10 off-road racing platform to provide responsive racing characteristics in all conditions.
XB2 suspension arms are the result of long-term testing of different designs and layouts. Length, thickness, flexibility, geometry, and materials used… these are all part of the concepts and details that are thoroughly reviewed to create optimum suspension arms.
The suspension arm itself is rigid enough to provide a responsive feel, yet soft enough for extreme durability. The exclusive composite mixtures used for suspension arms are a perfect balance between reliability and performance.
There are three different suspension arms available: medium (optional), 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. Caster can be adjusted with values 0°, 2.5°, or 5° using included caster bushings.
There are two different caster blocks available: medium (optional) and hard (included), each suitable for particular track conditions.
The 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.
To adjust track-width, additional offset wheel hex drive hubs are optionally available.
Integrated Suspension Settings.
Using eccentric suspension bushings – which are inserted into Swiss 7075 T6 aluminum suspension blocks – as well as additional shims and turnbuckles, the XB2 suspension geometry can be completely adjusted for :
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.
The dual-arm steering system is very simple yet effective. The steering system is fully bearing-equipped with 8 high-speed ball-bearings for very precise steering. The Ackermann is easily adjusted by quickly & easily changing the 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.
Ackermann is also easily adjusted by inserting a shim on the steering plate as well changing various graphite extension plates on the steering blocks.
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.
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.
Shock pistons are made from Delrin® and are molded using ultra-high precision moulds. All-new 2-hole pistons (1.6mm and 1.7mm holes) are now included in the set.
Variable Shock Mounting.
The 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 at the Carpet Edition either in front or behind the shock tower to adjust the weight balance.
The stylish and effective rear wing was designed to work perfectly with the XRAY XB2 body. Made from strong Lexan™ material, the wing is supported on the mounts by extra flat shims to better support and extend the life of the wing.
An optional thicker 1.5mm (#323511) rear wing is highly reliable with less chance of breakage, while at the same time influencing the performance of the car as well. The thicker wing gives higher traction and stability, but gives reduced steering.
The Carpet Edition includes front Lexan™ wing that is used to generate front downforce and is mounted directly on the front shock tower.
In specific track conditions when the rear of the car must be stabilized, an optional rear anti-roll bar (#362400) can be easily installed. The anti-roll bar is mounted to the rear roll center holder and can be adjusted via the included linkages.
Anti-roll bar wires of different thicknesses are optionally available for fine-tuning; the wire thickness is laser-engraved for easy identification.
The extensive 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 position, bump steer, wheelbase, Ackermann, adjustable shocks, adjustable rear diff, adjustable slipper clutch, and adjustable XRAY Multi-Flex™.
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.
The XB2 includes premium HUDY Graphite Grease which is a high-performance, advanced-technology semi-fluid lubricant which incorporates both extreme pressure additives and finely-dispersed graphite for load carrying. It is intended primarily for the lubrication of rotating parts and loaded gears. In addition to providing outstanding load carrying, it is formulated to have excellent adhesion and resistance to "fling-off" under extreme conditions. The grease reduces wear and increases parts life.
