Zero Kingpin Steering Blocks
The super-lightweight composite Zero Kingpin steering blocks are a genuine innovation in design and functionality. Each block features an inset steel bushing that is molded into the steering block itself, ensuring a wobble-free and ultra-tight steering block assembly.
This enables the kingpin screws to be firmly held in the steel threaded bushing while the end of the screw is self-locked in composite to prevent the screws from loosening during racing. The molded-in steel bushings allow the steering blocks to turn freely, ensuring precise steering action. The super-tiny steering blocks are molded from lightweight, very strong and durable composite material.

Lightweight Suspension Blocks
The new-concept steering block is taken from 1/10 electric off-road cars, providing zero kingpin steering — the steering block rotates in an absolute vertical position so that the angle does not change. The new steering block gives a better steering radius which greatly improves the handling and makes the car even easier to drive on all tracks and provides more steering into corners. The steering block features a single optimized Ackermann position.

The tiny size of the steering blocks was achieved by using new lighter ball-bearings. The inner bearing (13x19) carries a heavier load where the CVD drive shaft outdrive rotates, while the outer bearing (8x14) is newer & lighter than before to reduce unsprung weight. The two ball-bearings are further away from each other which improves stability in the mounting and holding of the wheel axles.

(click to enlarge)

Caster Blocks
Each 1-piece lightweight caster block has the new zero kingpin suspension geometry, and each car is equipped with an optimum preset 10° caster block. The optimized caster angle is integrated and non-adjustable. The angle of the caster block + 10° angle of the front chassis kick-up with the suspension holders = total 20° caster.

Centralized Design
With the narrow chassis design, all the internal components were repositioned. The engine was placed as close to the centerline as possible while still keeping the center drivetrain in the most effective locations. To balance the weight of the engine, muffler, and fuel tank, the center differential was placed more to the right with the electronics strategically placed in a curved shape around the central differential. All this helps to keep the weight as close to the center as possible. The all-new centralized design improves side-to-side balance.

CVD Driveshafts
The CVD drive shafts are lighter yet still are the strongest that a buggy can be equipped with. All four CVD drive shafts are manufactured from exclusive HUDY Spring Steel™, the unique self-developed highest-strength material.

The CVD wheel axles are carried more safely in the steering blocks and rear uprights thanks to greater distances between ball-bearings. Additionally, the CVD assemblies are very secure and safe due to the connecting pin (which connects the shaft to the wheel axle) being located within a ball-bearing, thus ensuring that the pin will never fell out and preventing drive shaft disconnections.

The wheel axle part of the CVD is hand ground for maximum precision to ensure a perfect precise fit in both suspension ball-bearings… guaranteeing a perfect wobble-free fit and rotation.

Wheel Axles
Wheel axles and wheel nuts are made from lightweight yet super-strong aircraft aluminum, hard-anodized for increased lifespan and low wear. The new suspension is slightly narrower which enables the use of optional offset wheel axles for fine-tuning your XB9 for different racing conditions.

Differentials
Rubber-sealed composite differential housings are manually precision ground after the molding process to guarantee a perfect fit with no vibration. Differential gears are made from pressed steel, heat treated, and machined for ultra-precision and smooth operation.

Diff outdrives are made from premium HUDY Spring Steel™ and the central diff outdrives are individually ground for highest precision. The diff outdrives are specially-hardened to increase the lifespan, and the diff outdrive area which is inserted into ball-bearing is additionally ground to ensure a very tight fit and precise rotation. The openings of the diff outdrives were designed to keep the drive shafts in the diff outdrives even during maximum suspension downtravel.

Diff Gears & Drivetrain Ratio
Diff main gears are manufactured from HUDY Gear Steel on a precision manual gear machine. This material was specially formulated and developed for use in gears. All gears are hardened to provide the longest possible lifespan.

A wide range of different gears — spur gear, clutchbell, crown gear — is available for perfect set-up and adjustment for particular racing conditions.

Clutchbells are available in sizes of 15T, 16T, and 17T.
Spur gears are available in a range of 41T, 42T, and 43T.


The drivetrain ratio is all-new for the XB9, allowing for more aggressive acceleration, and aggressive yet easier handling.

Front and rear differentials feature 43T crown gears with 10T pinions for a 4.3:1 primary ratio.

The central differential features 42T spur gear with a 16T clutchbell for a 11.29 internal ratio.

The final ratio of the XB9 is within the range of 10.37–12.33.

Center Differential Access
Access to the center differential is super easy by releasing the upper deck with only four screws. The lower center diff housing is designed to accommodate optional spur gears and the stands were lowered by 2.5mm to keep the weight as low as possible and allow smaller central diff gears to be used. The center diff housing stands hold the effective brake system.

1-piece Electronics Assembly
The 1-piece electronics assembly is very compact and can be quickly & easily removed for servicing and cleaning. You need only to release a few screws from the bottom of the chassis to remove the entire electronics assembly from the car.

The large molded radio box features a very clean design and layout that places the weight in key areas for proper balancing. The batteries are placed along the centerline of the chassis, and the lightweight receiver is placed on its side. The very easy-to-access radio box is mounted on the side of the radio plate and is releasing by only a few screws.

For racers not using a radio switch, a handy molded cover is included to help guarantee a leak-free radio box. The tight antenna tube holder ensures that the antenna tube stays attached even if the car flips.

The radio box was redesigned to fit to the new chassis, and the battery cover was redesigned to hold the batteries more securely.

HUDY Spring Steel™ Steering Turnbuckles
All turnbuckles in the XB9 are manufactured from special HUDY Spring Steel™ material for turnbuckles, resulting in stronger turnbuckles with a tougher core.

With the narrow steering plate and narrow steering stands, the turnbuckles were appropriately resized and elongated. Relieved steering ball-joints fit better into the wheels.

XRAY Premium Silicone Oils
The XB9 includes new XRAY Premium Silicone Oils manufactured in Europe by a specialized premium silicone oil manufacturer; these new oils were exclusively created for XRAY. Each batch of premium oil is laboratory tested and calibrated to ensure the highest possible consistency and quality batch-to-batch. Based on industry-standard cSt rating, the new line of oils will be easy to identify, adjust, and feel.

When following any set-up sheets by XRAY or XRAY Team Drivers, you can be sure that the oils you will get for your car will be exactly same as the oils used by the factory racing team, thus ensuring very exacting setups and handling.

Engine Mounts
High-grade CNC-machined aluminum engine mounts are machined from lightweight alloy and help to dissipate engine heat. The engine mounts are easily adjustable from the bottom of the chassis to obtain proper gear mesh.

The engine mount is all newly designed, it is longer and goes up to the front engine bearing which provides higher reinforcement of the chassis in the longitudinal direction and in jumps will minimize chassis bending between the clutchbell and spur gear.

Brake System
The XB9 features the well-proven high-performance braking system that is so strong and precise and dependable that is makes slowing and stopping a profoundly exhilarating experience. Coupled with the car’s balanced load distribution, the extraordinary control imparted by the braking system gives you complete confidence as you pitch the car into corners.

XRAY focused on all of the smallest details when designing the brake system. The laser-cut, precision flat-ground ventilated steel brake disk allows for fade-free braking in conjunction with the special high-grip Ferodo® brake pads installed on laser-cut backing plates. The brake disk is small, slim, and very light. The precision hand-grinding allows true, wobble-free rotation. Brake inputs are transferred precisely to the brakes via rigid high-precision machined brake cams. The brake disk and brakepad backing plates are specially heat-treated for maximum lifespan.
