New Swiss 7075 T6 aluminum shock towers feature lowered shock mounting positions for both the front and rear suspension. The lower mounting positions increase the overall stability of the car across all surfaces, as well as help increase cornering speeds. By carefully selecting the new tower geometry, the single row of shock mounting positions simplifies the set-up process to optimize performance for any track condition.

The front & rear shock towers are CNC-machined from 4mm Swiss 7075 T6 aluminum for strength and durability. The front shock tower features 4mm shock mounting holes for increased durability and rigidity.

The new XB8E shock bodies and shock shafts were shortened to match the new lowered shock towers and lowered mounting geometry, while maintaining proper suspension travel.

The shorter XB8E shocks carry over multi-adjustable 3-in-1 shock caps with 4 bleed holes with 3 different seal choices – ribbed membrane, cell membrane, or O-ring. The shorter shocks feature 3 different assembly alternatives – emulsion / rebound / zero rebound, with each one suitable for different track conditions.

The lower shock ball joint features a lock extension that fits into the lower collar, reducing the chances of the retainer separating from the ball joint and unseating the spring in a crash.

Oversized big-bore shocks featuring 16.2mm I.D. shock bodies and are externally threaded with an adjustable collar for quick & easy spring preload adjustment. The shock bodies are hard coated in a titanium color and feature a 1-piece aluminum lower cap.

The XB8 comes with 4 Dots front springs and 3 Dots short (82mm) rear springs.

3-in-1 shock caps allow assembly in 3 different configurations – emulsion / rebound / zero rebound, to match shock dampening characteristics to various driving styles and different track conditions.

The Emulsion configuration uses an O-ring to seal cap to body, mixing oil and air inside the shock. Typically provides excellent traction on a variety of surfaces and is suggested as a starting point for most typical track conditions.

The Rebound alternative using the cell membrane is best matched to lower traction and flat slippery tracks. This shock set-up has the most rebound out of the three build options.

The Zero Rebound configuration created by using the ribbed membrane is better suited for super bumpy tracks. This set-up has no rebound.

The all-new composite cable holders provide clean cable management, limiting the risk of cables getting stuck in gears or unplugging the battery connectors. Once assembled, the cable holders improve the overall look and cleanliness of the battery and motor wires.

Mounting of the new cable holders is very simple, adding only a few more screws to the assembly process.

The new front & rear gearbox front cases were modified with provisions for the anti-roll bar centering collars. The new anti-roll bar collars minimize unwanted movement and improve the precision of the anti-roll bar functionality.

Front & rear bulkheads feature a semi-split design for easy diff access while adding the valuable diff height adjustment. The bulkhead also aligns the front central driveshaft with a reduced operating angle for less friction and reduced wear on the CV joint components and improved driveline efficiency.

The XB8 bulkheads allow fast and easy differential access for setup changes or servicing by removing only 4 screws from the upper gear box cover while the lower section remains mounted to the chassis with the lower arms and suspension holders installed. This super-fast diff access is featured on both the front and rear gearboxes.

To increase overall traction in all track conditions, the front anti-roll bars used are 2.2mm and the rears to 2.4mm.

Anti-roll bars, manufactured from spring steel material, are easily mounted to front & rear diff cases with easy adjustment using the adjustable linkages.

Anti-roll bar wires of different thicknesses are optionally available for fine-tuning.

Steering blocks feature all-new steering geometry thanks to all-new 3 dots carbon steering plates. The new geometry helps to improve stability and cornering speed and features also increased Ackermann, with the outside wheel turning less, which yields improved drivability and lowered lap times.

Steering blocks from hard composite material provide responsive feel especially on bumpy tracks and retain free suspension movement in dusty conditions for better consistency.
The steering blocks are super lightweight yet extremely strong, featuring a larger outside 8x16x5mm ball-bearings for increased reliability and lifespan.

The all-new 3 dots carbon steering plates update Ackermann geometry, improving the stability and cornering speed of the car. The new geometry features increased Ackermann, with the outside wheel turning less, which yields improved drivability and lowered lap times.

Ackermann can be easily adjusted on the machined Swiss 7075 T6 steering plate as well to ensure highest reliability and strength.

To improve the out-of-the-box geometry, the XB8 now includes both front & rear wheel hubs with a +1mm off-set which is the most favorite choice for most of the track conditions.

Ultra-lightweight 17mm wheel hex drive hubs are CNC-machined from Swiss 7075 T6 black-coated aluminum.

The alu hex hubs are specially machined to reduce rotating weight while guaranteeing wobble-free wheel mounting.

A new smaller center differential assembly significantly reduces rotating mass to create more forward drive out of the corners. The all-new composite spur gear reduces rotating mass and makes for quieter vehicle operation. Reducing rotating mass improves responsiveness for better control and handling, improves battery life and reduces equipment operating temperatures.

The smaller center differential has the same differential case as the front & rear differentials, simplifying spare parts management.

The complete smaller center differential with composite spur gear significantly reduce the overall driveline mass.

Both front and rear differentials are identical for easier maintenance and servicing.

The large volume front and rear diffs feature high capacity cases, strong diff pins, and large internal gears with more teeth for improved differential action, consistency and overall reliability. The larger volume of the differential and the shape of the gear teeth reduce oil overheating.

The shorter rear central driveshaft matches the shorter wheelbase of the XB8E chassis plate. The rear central drive shaft is 111mm long.

All XB8E drive shafts are manufactured from world-renowned HUDY Spring Steel™, resulting in some of the thinnest and most durable drive shafts found in any RC vehicle. All XRAY drive shafts and outdrives are hardened with a proprietary hardening process to provide unsurpassed lifespan & reliability.

Reinforced front and rear bulkheads were updated for added strength to ensure higher reliability and to improve the seal between the main bulkhead and cover plate. The revised bearing inserts also feature improved dust resistance and prevent debris from entering the bulkhead assemblies while offering the valuable differential height adjustment.

The diff height adjustment of the semi-split bulkheads uses eccentric bushings to set the diff position. The diff height has 3 different settings. The diff height adjustment is a vital tuning option that allows quick set-up adaption for all different track conditions.

The ideal position will vary depending on the track conditions and ride height.

The design of the semi-split bulkhead allows to adjust the angle of the CV joint depending on the track conditions, traction of the track and ride height used.

At the high traction tracks a lower ride height is used and thus the diff placed in upper position to keep the drive shafts straighten and corresponding CV joint also in upper position.

At the low traction tracks an increased ride height is used and thus the diff placed in lower position to keep the drive shafts straighten and corresponding CV joint also in lower position.

The differential crown gear and bevel drive gear feature specially designed profiles of the 46T and 13T gears for a perfectly matched engagement for smoother operation, less drag and significantly longer lifespan.

The high-volume differentials improve vehicle control and consistency over long runs and enhance reliability. The differentials feature larger capacity cases and larger internal gears with more teeth for improved differential moment. The larger oil volume and the shape of the gear teeth reduce overheating for improved consistency. The stronger diff pin design also improves reliability.

The semi-split bulkhead design and compact front bumper allows direct access to the differential while the entire suspension assembly remains mounted on the car.

The steering system includes Ackermann plate and graphite servo saver component shape to work with the semi-split bulkhead.

To ensure servo saver reliability, the servo saver parts are moulded from graphite material which is more resistant and efficient in dusty conditions. The dual-arm steering system is simple yet effective, featuring an integrated and easily adjustable servo saver, and a Swiss 7075 T6 aluminum steering plate.

The conical spring is longer and stronger, ensuring more precise steering and improved reliability.

Ackermann is easily adjusted by changing steering link mounting positions on the steering plate. Bump steer is adjusted by inserting shims between the steering plate and steering linkage.

Front upper arms have additional mounting holes for the optional front upper arm wings. The wings increase downforce on the front suspension for increased traction and helps to keep the buggy nose down.

Optional wings are available in Lexan and Carbon alternatives.

To ensure the performance and reliability, the Pivot Ball suspension arms and optional C-hub suspension are molded from special composite mixtures that can be selected based on temperature and track conditions. The stock rear suspension arms are molded from Hard composite mixture that makes the car easier to drive. The included front lower and upper arms are made from our Medium composite mixture. The optional front lower C-hub suspension arms are available in multiple mixtures as well.
