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 XT8 is truly a masterpiece.

Unique E concept.

The XT8E features an all-new unique E concept with two different layout alternatives.


  1.  Rear motor position with a single battery position on the left side

Standard e-truggy position places the battery on one side with the speed control, and the motor, servo and receiver on other side of the chassis.

Suggested for very low grip traction conditions or when more chassis roll is desired. The center of gravity of this layout is generally higher due to battery orientation.

  1.  Front motor position with saddle pack batteries

Second alternative places the motor in front of the center differential opposite the servo, and uses a split, saddle pack battery layout. The motor has better cooling in this front location and the split batteries typically maintain lower temperatures during each run.

Suggested for bumpy tracks and when higher corner speed is required.


The new XT8E chassis is wider in the rear section to increase stability in high speed corners and on bumpy track surfaces. The chassis plate features machined grooves that match the servo saver posts to prevent any rotation, making assembly easier and securing the steering components during extreme chassis flex situations.

An optional graphite brace can be mounted on the chassis to decrease flex in the rear section to help increase stability.

The XT8E’22 chassis features new positions to mount weights for additional weight balance adjustment.

The chassis is CNC-machined from 3mm high-quality Swiss 7075 T6 aluminum; strategically machined in low-stress areas and then anodized to make it as light as possible without affecting strength or rigidity.

Chassis Balance.

The XT8E’22 chassis features new positions to mount weights for additional balance adjustments. All the central positions are placed in an absolute chassis center for optimal weight balance.

Suspension Arms.

Both front and rear suspension arms are redesigned with a new stronger, reinforced design to maintain rigidity in extreme conditions and higher temperatures. These stiffer suspension arms improve the XT8’s stability and predictability in high speed corners.

Servo Saver.

The servo saver features a new conical spring that is longer and stronger. The new spring ensures more precise steering and improved reliability.

The servo saver posts feature a new keyed design to prevent the posts from spinning on the chassis for easier assembly and to prevent the posts from twisting loose during a run.

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 a Swiss 7075 T6 aluminum steering plate.

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.

Servo Saver Top Deck.

The servo saver top deck was also redesigned. The new top deck features additional clearance to prevent binding even if it is overtightened so the steering will always move freely. Fits both XT8 and XT8E

Servo Holder.

To accommodate the two different electronic layout choices there are two different servo holders included in each XT8E kit. One to fit the single side battery layout, and the other for the saddle pack layout. Servo horn position is moved more forward and uses a shortened link.

Battery Holders - Saddle Pack.

To accommodate the two different battery positions there are two different battery holders included in each kit.

Saddle pack alternative – features all-new tweak-free split battery holders 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.

Battery Holder - Brick.

To accommodate the two different battery positions there are two different battery holders included in each kit.

Brick alternative – features a battery holder for one large 4s battery pack or two standard 2s battery packs side by side. The holder is moulded from a harder material to reduce flex. In this configuration, the battery pack(s) is installed in this left side location together with the ESC.

Electronics Plate.

The saddle pack battery layout features a new molded 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. 

Shock Towers.

The front shock tower features updated geometry with new shock mounting positions that are 8mm lower compared to previous models. The new shock geometry, combined with the improved arm stiffness, helps to improve the corner speed of the XT8’22.

Front Shock Absorbers.

Front shock absorbers were updated to match the new shorter front shock tower. Together with the lower shock towers, the shocks increase stability, corner speed and predictability on high-speed tracks.


I designed and hand-made my first off-road cars back in 1986, and they dominated the racing scene thanks to unbeatable reliability and superior performance. Years later in 2004, we started our first mass-production XRAY XB8 platform based on our long-term experience & knowledge, followed soon thereafter by the XT8 truggy platform.

Since the release of the XT8 platform, we have continued our dedicated work of refining the platform to bring forth the latest improvements & innovations. With our focus on no-compromise performance, the XT8 has undergone a major platform upgrade to ensure the XT8 will stand out in the crowd and take you to the Winners Circle.

XT8E Concept.

The XT8E is a typical XRAY: premium, professional, high competition for the most demanding racers, developed with attention to the smallest details, and backed by premium service & support…a luxury masterpiece.

Some information shown below may include details from previous kits, and it may vary slightly from current kit specifications.

C-hub Suspension.

The XT8 front C-hub suspension is using zero kingpin steering blocks with interchangeable steering plates and CVD drive shafts.

Steering Blocks.

The super-lightweight composite zero kingpin steering blocks feature exchangeable steering plates to easily adjust the Ackermann.

The steering blocks feature an inset aluminum bushing that is molded into the steering block itself, ensuring a lightweight, precise and durable steering block assembly. This enables the kingpin screws to be firmly held in the aluminum threaded bushing while the end of the screw is self-locked in composite to prevent the screws from loosening during racing.

The molded-in aluminum bushings allow the steering blocks to turn freely ensuring precise steering reaction. The super-tiny steering blocks are molded from a lightweight yet very strong and durable composite material.

Caster Blocks.

The unique C-hub suspension on the XT8 features Integrated Adjustable CasterTM which enables adjustment of the single C-block through the entire caster angle range; no optional caster blocks needed!

The C-block features an inclined kingpin design for increased steering and stability.

The C-hub suspension includes now steel caster bushings and ball mounts instead of composite versions, giving increased strength & reliability.

Rear Uprights.

The rear uprights feature larger outside 8x16x5mm ball-bearings for increased reliability and life-span. To expand the set-up choices there are three roll-center adjustment positions.

The smart design allows the same upright to be used on both left & right sides. The rear uprights feature integrated geometry adjustments for camber, upper and lower roll center and wheelbase.

Two shims allow positioning the hub forward/backwards along the outer suspension pin to adjust wheelbase.

Side Guards.

The side guards incorporate a larger bottom radius to make the truggy more stable on rough tracks, while increasing longitudinal flex. The side guards are moulded from special composite mixture for increased flex which helps to generate more traction.

I.S.S.™ Suspension Holders.

The aluminum suspension holders feature Integrated Suspension Settings (I.S.S.™) which allows for super-fast & easy suspension geometry adjustment.

Using eccentric suspension bushings inserted into aluminum suspension blocks – as well as suspension shims – the XT8E suspension geometry can be completely adjusted:

• Caster
• Camber
• Front & rear toe
• Front & rear roll center
• Front kick-up
• Rear anti-squat
• Wheelbase
• Track-width

A complete set of various eccentric bushings is included for complete suspension geometry adjustment. The bushings are inserted into aluminum holders which are machined from premium Swiss 7075 T6.

Steering System.

The dual-arm steering system is reliable and has improved steering characteristics.

Molded graphite servo saver makes the steering more resilient & efficient in dusty conditions. The alu steering plate gives more aggressive steering characteristics, the composite upper top deck ads flex to help steering, and the steering pivot balls feature backstops for increased reliability.

Ackermann can be adjusted quickly & easily by changing steering link mounting positions on the steering plate.

Bump steer is easily adjusted by inserting shims between the graphite steering plate and steering linkage.

Drive Shafts.

The XT8 features CVD drive shafts both front & rear.

All 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.

The central larger & stronger outdrives feature protective rubber boots, thick 3mm pins, and protective locking rings.

Diff Bulkheads.

The diff bulkheads are reinforced and strengthened for increased reliability. The bulkheads are an important chassis component, housing both the front & rear differentials and providing mounting points for the suspension mounts and shock towers.

The super-strong front & rear bulkheads can 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.

Gear Differential.

The high-volume gear differentials were designed for increased reliability & performance. Differentials feature high-volume cases, and larger internal gears with more teeth for improved differential movement. The larger volume of the differential and the shape of the gear teeth reduce oil overheating. To increase reliability, diff pins have stronger design. The differentials give increased traction and reliability, especially in long runs.

Internal Diff Gears.

Internal diff gears increase differential reliability and reduce diff oil overheating. The 20T and 10T gears have a larger size and a greater number of teeth to ensure more precise fitment and engagement. Pressed-steel differential bevel and satellite gears are heat-treated and machined for superior precision and smooth operation.

Diff Outdrives.

Diff outdrives accommodate the stronger diff pins. The front longer diff outdrive adapters ensure that the drive shafts will not fall out, even in extreme crashes at full steering lock.

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.

Shock Springs.

XT8 shock springs offer a mix of progressive & linear characteristics. XT8 springs are slightly progressive, but under more compression change characteristics to become more linear. This gives excellent feeling and feedback in all different track conditions.

These XRAY shock springs, like all other XRAY springs, are manually measured, selected and matched into pairs to guarantee precisely equal length and damping characteristics.

Two types of springs are optionally offered:

• Linear: Spring rate is constant during the entire spring compression. Springs with different spring rates are available as optional tuning parts.

• Progressive: Spring rate is not linear, but rather the spring rate get progressively heavier the more the spring is compressed. As the truggy initially enters the corner, the spring works like a softer spring to provide maximum traction. As the chassis begins to roll in the middle of the corner, the spring rate progressively increases until it works like a stiffer spring which allows the truggy to maintain maximum cornering speed.

Shock Pistons.

Ultra-precise shock pistons with 6-, 8- and 10-hole options. The big-bore pistons are molded from tough, race-proven Delrin® material to provide smooth action and durability. The precision molding production process ensures perfect piston roundness, ensuring that the pistons move super-smoothly inside the shock bodies for identical, perfect action in all four shocks.

Wheel Hubs.

Ultra-lightweight 17mm wheel hex drive hubs with +5mm offset 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.


To guarantee maximum reliability, all turnbuckles are manufactured from special HUDY Spring Steel™ material for turnbuckles with a tougher core. These turnbuckles are used for front & rear upright linkages, steering system, and servo saver.


A full set of 24 high-speed, blue-sealed ball-bearings are used throughout the drivetrain to ensure maximum efficiency. 

Anti-Roll Bars.

Spring steel anti-roll bars – carried over from the XB8 platform – are used to stabilize the truggy. The 2.6mm front anti-roll bar improves the corner speed.

The front & rear anti-roll bars are easily mounted to the diff cases and can be fine-tuned using the adjustable linkages.

Optional anti-roll bar wires of different thickness are available for fine-tuning your set-up.

Body Mounts.

The body is mounted on two strong composite body mounts with foam cushions both front and rear. There are two types of rear body mounts included depending on the type of the body used.

Wing Holder Brace.

To help prevent rear bulkhead breakage during crash impacts, the rear wing mount features a wing holder brace that transfers crash impact energy from the wing and shock tower to the chassis instead of directly to the bulkhead.

Rear Wing Holder.

The rear wing holder is a super-slim, 1-piece design that reduces weight and increases strength.

The complete wing mount is 40% lighter than the previous version, significantly reducing the weight behind the rear suspension and lowering the CG. The wing holder provides maximum stability while still allowing some flex during impacts.


The stylish and effective rear wing was designed to provide the appropriate amount of downforce and generate required stability for the truggy. Made from a strong special composite mixture, the wing was designed to survive severe abusive and extreme crashes while keeping its shape.

Rear wing holders are made from a special composite mixture to withstand abuse and crashes, and feature several different wing mounting positions.

Silicone Oils.

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 truggy are exactly same as those used by the factory racing team, thus ensuring very exacting set-ups and handling.

HUDY Chem Series.

Graphite Grease.

The XT8 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. HUDY Graphite Grease reduces wear and increases parts life.
