The XB8E shares a majority of its parts with the ultra-successful XB8 platform with several details fine-tuned for the electric buggy class. Wherever possible, the XB8 and XB8E share suspension and driveline components to streamline spares and tuning parts between the two cars without making any compromises to on-track performance. This minimizes the number of extra parts needed to support both nitro and electric editions even smaller for the extremely durable recent generation XRAY 1/8 off-road platform.
The XRAY XB8E platform displayed its incredible performance advantage by winning the European Championships in the hands of Jean-Pierrick Sartel.
Made in Europe.
Designed, developed, and fully manufactured in-house at the XRAY factory in Slovakia, Europe, using the most high-tech German & Swiss machines and premium European materials, crafted with XRAY’s legendary attention to detail by our artistic production specialists. The XB8E is truly a masterpiece.
Shorter Wing Holder.
New wing mount moves the wing forwards to create more downforce over the rear wheels and increase rear traction.
The XB8’s molded wing was redesigned for a more forward position to create more downforce over the rear suspension. The shape of the wing increases the stability of the car in all conditions and is legal under the latest IFMAR wing specifications.
Central CVD Shaft Universal Joint.
To increase reliability and strength, the M4 set screws on the central CVD universal joints were replaced by more robust M5 set screws to eliminate stripping the screw during installation or maintenance.
Central CVD shaft universal joints are made from world-renown HUDY Spring Steel. Strategically machined for toughness and reduced weight without compromising strength. Fits front & rear central CVD drive shafts.
New graphite rear shock tower improves traction in all track conditions. CNC-machined from extra-thick 4mm premium-grade graphite, the shock tower features multiple shock positions and multiple roll center adjustment positions.
Steering blocks from a harder composite material provide a more 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.
New harder rear uprights maintain stability in all track conditions. The hard material also improves the handling in hotter conditions and better maintains it shape for improved bump absorbing. The uprights are super-strong and feature a larger outside 8x16x5mm ball-bearing for increased reliability and lifespan.
To improve the reliability the servo holder has new reinforced design. The servo holder is designed to fit the saddle pack layout.
The XB8E chassis layout allows to install saddle pack battery alternative as well optional brick battery alternative.
The battery holder features tweak-free split battery holder to mount the saddle packs. This battery holder will accommodate both standard and ‘shorty’ packs, with the shorty packs having the added ability to move front/back for additional weight balance adjustment.
The saddle pack battery layout features a moulded electronics mounting plate that is positioned next to the servo. The speed control, receiver and transponder are all installed on this plate for easy removal and maintenance.
The servo saver features a conical spring that is longer and stronger. The spring ensures more precise steering and improved reliability.
The servo saver posts feature the locking system that ensures the servo saver setting will not change while running.
To ensure servo saver reliability (especially in dusty conditions), the servo saver is 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 easily-adjustable servo saver and Swiss 7075 T6 aluminum steering plate.
Ackermann is easily adjusted by quickly & easily changing steering link mounting positions on the steering plate. Bump steer is easily adjusted by inserting shims between the steering plate and steering linkage.
Servo Saver Top Deck.
The top deck features holes for the servo saver that ensure the servo saver will not lock when overtighten and will always work freely.
The top deck features an extra hole for the front chassis brace. When built using the single sided battery configuration, the left mounting hole is used to prevent driveshaft collision with the chassis brace.
Fits both XB8 and XB8E.
The XB8E design allows to accommodate either the C-hub or Pivot Ball suspension. The included Pivot Ball suspension can be easily exchanged for the optional C-hub suspension to accommodate to the particular track conditions.
The optional C-hub is perfectly suited for smooth and short technical tracks & smooth surface conditions. At these track conditions the C-hub suspension generates increased frontward traction as well increased overall traction with enhanced steering.
The C-hub suspension includes lower suspension arm, steering block with Ackermann plate, C-hub, camber link & Ackermann steering plate.
The rear brace mounting position on the chassis was moved rearwards to improve chassis flex and give increased traction.
The chassis features chamfered front edges which prevents dirt pick-up when the chassis contacts the track. The chamfered edges will not “cut” the dirt, but rather the dirt will slide along the chamfered edges and not get stuck at the front of the chassis.
The side guards were moved 4mm rearwards to ensure that under full throttle and full steering lock the inflated tires will not contact the side guards and can operate freely.
The mounting of the chassis brace to the bulkhead eliminates transfer of energy from the suspension via shock towers to ensure more precise landings and more off-power traction.
The included rear brace is moulded from a medium-stiff composite mixture for improved flex & rigidity, and allows the mounting of optional graphite inserts to reinforce the chassis brace to make it even stiffer for particular track conditions.
Side guards feature a larger bottom radius to give better stability on rough tracks. The radius of the side guards increases the car’s longitudinal flex. The side guards are moulded from a special composite mixture for increased flex that helps generate more traction.
The tough composite side guards protect the car, muffler, and fuel tank from side impacts. The side guards perfectly fit the chassis and seal against dirt.
Optional side guard braces allow for very efficient and easy chassis flex adjustment to adjust the handling of the car to different track conditions. By adding the graphite braces, the entire chassis is reinforced and stiffer flex will improve handling in high-traction conditions.
To improve the performance and reliability, the Pivot Ball suspension arms and optional C-hub suspension are molded from a new composite mixture. The rear suspension arms are molded from an all-new, extra-hard composite mixture that makes the car easier to drive. The front lower and upper arms feature a composite mixture change from soft to medium. The optional front lower C-hub suspension arm is molded from a hard composite mixture.
I.S.S.™ Suspension Holders.
The aluminum suspension holders feature Integrated Suspension Settings™ (I.S.S.) which allows for quick & easy suspension geometry setting. To accommodate the longer rear suspension arms, narrower aluminum suspension holders are used.
Using eccentric suspension bushings inserted into aluminum suspension holders – as well as additional suspension shims – the XB8 suspension geometry can be completely adjusted in mere seconds.
Diff bulkheads are an important chassis component, housing both the front and rear differentials and providing mounting points for the suspension mounts and shock towers.
The super-strong front & rear bulkheads withstand rigorous impacts and other abuse during racing conditions. The bulkheads have minimized ball-bearing play, resulting in increased gear teeth lifespan and minimized gear stripping.
The specially-designed ball studs eliminate steering lock and allow greater steering radius. The integrated backstops ensure that the pivot balls do not disconnect in crashes.
Ackermann is easily adjusted on the machined Swiss 7075 T6 steering plate to ensure highest reliability and strength.
The rear drive shafts are 93mm long and help reduce the chances of bind in the outdrives after extreme jump landings that could cause handling irregularities or damage.
All XB8E drive shafts are manufactured from world-renowned HUDY Spring Steel™, resulting in some of the world‘s thinnest yet most durable drive shafts used in off-road cars. All drive shafts and outdrives are hardened with a proprietary hardening process to provide unsurpassed lifespan & reliability.
To increase the reliability and free movement of suspension even in the extremely dusty conditions, the pivot ball cups are moulded from a graphite material that ensures more free movement even when dust builds up.
To reduce weight and lower the CG, the front upper pivot balls are combined with a steel threaded part for maximum strength. The aluminum ball is machined from premium Swiss 7075 T6 and additionally hard coated for extended lifespan.
To accommodate the geometry, the XB8E includes rear wheel hubs with a +2mm off-set while the front features the +1mm off-set wheel hubs.
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.
The XB8E is a conventional shaft-driven 4WD off-road car featuring:
- Front & rear gear differentials with adjustable oil viscosity, featuring 46T crown gears and 14T pinion gears
- Central differential with adjustable oil viscosity, featuring 46T spur gear
- Front & rear universal drive shafts, and central CVD drive shafts
Both front and rear differentials are identical for easier maintenance and servicing.
The Large Volume diffs feature higher capacity cases, stronger 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 help reduce oil overheating.
Central Diff Gear.
The central differential is an extra-large size for increased reliability and performance. The differential is over 5mm larger, with an increased oil capacity to reduce oil overheating in long runs, helping to keep differential performance as consistent as possible.
Internal Diff Gears.
The 20T and 10T internal diff gears are larger to ensure reliability and reduce diff oil overheating. The greater number of teeth ensures more precise fitment and engagement.
Pressed-steel differential bevel and satellite gears are heat-treated and machined for superior precision and smooth operation.
Updated diff outdrives accommodate the stronger diff pins.
To reduce rotating weight, the super-lightweight diff outdrives are machined from HUDY Spring Steel™ which allows unnecessary material to be removed to further reduce weight without affecting durability. The inner portions of the outdrives are additionally hand-ground for maximum precision and fitment into the diff case.
All outdrives are hardened using HUDY’s own special hardening process for extended lifespan and reliability.
Diff Gears & Drivetrain Ratio.
To improve the acceleration of the XB8E the central spur gears are larger.
Differential 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 gears and pinion gears — are available for perfect set-up and tailoring to particular racing conditions.
Pinions are available in sizes of 12T, 13T, 14T, 15T, 16T and 17T
Spur gears are available in a range of 46T, 47T and 48T
Rear Wing Holder.
The rear wing holder has a super-slim, 1-piece design that has reduced weight and increased strength.
The complete wing mount is 40% lighter than the older version, considerably reducing the weight behind the rear suspension as well significantly reducing the CG. The wing holder has maximum stability while still allowing flex during impacts.
Wing Holder Brace.
To help prevent rear gear box breakage during crash impacts, the rear wing construction features wing holder brace that transfers crash impact energy from the wing and shock tower to the chassis where it is centrally resolved.
The wing holder brace includes an integrated body post as well.
The motor is connected to a mounting plate, with the assembly then inserted into an integrated motor holder/drivetrain support. The design of this system allows quick and easy motor rotation to adjust gear mesh, and yet clamp.
The motor mount machined from Swiss 7075 T6 and is 2mm wider compared to older version for improved durability.
The XB8E shock bodies feature composite lower shims for improved shock shaft movement. The shock caps feature 4 bleed holes for easier building and more precise rebound control. The longer shock shafts allow more suspension travel. Multiple shock membrane choices are available to tune the suspension to a wide variety of track conditions.
Oversized big-bore shocks featuring 16.2mm I.D. shock bodies are externally threaded with an adjustable collar for quick & easy spring preload adjustment. The shock bodies are hardcoated in a titanium color and feature a 1-piece alu shock cap.
The XB8E now includes the 4 Dot front springs.
The XB8E includes the 4-dot front shock springs for stability. XRAY shock springs are manually measured, selected and matched into pairs to guarantee precisely equal length and damping characteristics.
Ultra-precise shock pistons feature 6-, 8- and 10-hole options. The big-bore pistons are molded from tough, well-proven Delrin® material to provide smooth action and durability. The precision molding production process ensures perfect piston roundness after production, so that the pistons move super-smoothly inside the shock bodies for identical perfect action in all four shocks.
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.
To guarantee maximum reliability, all turnbuckles are manufactured from a special blend of HUDY Spring Steel™ which is specifically formulated for turnbuckles. The turnbuckles have a tougher core, making them very well suited for the steering system and rear upright linkages.
HUDY Exclusive Silicone Oils are manufactured in Europe and each batch is laboratory tested and calibrated to ensure the highest possible consistency and quality from batch to batch. Based on the 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 are exactly same as those used by the factory racing team, thus ensuring very exacting set-ups and handling.
HUDY Chem Series.
XB8 “Eazy” Body.
The “Eazy” Body was created after significant time spent testing dozens of different alternatives until the final design was selected. The design of the body improves the handling for all skill levels, from local racers to World Champions. The “Eazy” Body makes the XB8 more stable at speed and more reactive in the corners.
The redesigned sides of the body improve stability at higher speeds. The round front cab and profile make the XB8 easier to drive. Some of the redesigned down force areas increase the speed of the car. The central fin on the roof help control the car more precisely making handling more predictable. Overall, the “Eazy” body is the most significantly improved performance off-road body we have designed.
The front cabin was redesigned with a wider and cab forward design so both left and right sides generate matching downforce even with the cut-out opening for fuel tank.
The body is fully compatible with the XB8 and XB8E platforms.
Socket Head Cup Screws.
To increase lifespan and improve ease of servicing, socket-head cup screws are used instead of regular hex screws. The socket-head cup screws are stronger and more reliable, making it easier to work on the car.
A full set of 22 high-speed ball-bearings are used throughout the XB8E drivetrain.
Grease lubricated bearings are included for the pinion gears and diffs to increase reliability and lifespan, especially in dusty conditions. The remaining bearings are degreased and oiled with AeroShell® Fluid 12 to reduce drag and maximize driveline efficiency.
The XB8 includes premium HUDY Graphite Grease – a high-performance, advanced-technology semi-fluid lubricant which incorporates both extreme pressure additives and finely-dispersed graphite for load carrying. HUDY Graphite Grease 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 from “flinging off” under extreme conditions.
