Florida Carpet Champions 2023.
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.
After a decade of worldwide success with the XB2, we reached the point in time to re-evaluate the current platform and to incorporate all the latest experiences, knowledge and current racing trends into a fully redesigned 2WD buggy. The all-new XB2’24 brings a completely new platform with 75% of components being redesigned and updated, making it for a completely new XB2 platform.
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.
Made in Europe
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.
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.
All-new Front End.

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.
Motor Plate & Spur Gear Protector.
The super lightweight motor mount is machined from Swiss 7075 T6 aluminum and is a universal design that fits both Carpet and Dirt Edition gear boxes.
The molded composite gear protector prevents contact between the spur gear and the body. Moulded from strong, lightweight material, the cover helps to protect the body shell and spur gear, and it allows the body to be mounted lower without interference.
The motor plate is universal for both Dirt and Carpet edition.
Roll Center Holder.
Roll center holder fits the LCG gear box and features multiple roll center positions. The roll center holder also serves as the rear anti-roll bar mount.
An optional rear aluminum roll center holder features roll center positions in between the stock positions for additional tuning choices.
The roll center holder is universal for both Dirt and Carpet edition.
Motor Mount Brace.
The redesigned motor mount brace ensures optimum flex via a pivot ball mount that ensures side flex for increased traction.
The design of the car also allows removal of the motor mount brace to increase flex and to move the battery pack further to the rear to position more weight over the rear axles for improved rear traction.
The motor mount brace is 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.
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:
- design and shape of 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 carefully designed for the 2WD 1/10 off-road racing platform to provide responsive racing characteristics in all conditions.
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
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.
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.
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 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.
