Etwas früher als die 17er Version wurde der neue Nitro 1/8 Offroad-Buggy von Xray vorgestellt. Nach dem Ty Tessmann im Laufe der Saison zu Xray ins Team gekommen ist, waren wir gespannt, welche Änderungen in der neuen 2018er Version enthalten sind oder es eine komplett überarbeitete Version werden würde. Nun ist die Katze aus dem Sack.
Ein paar neue Features sind u.a.:
- Komplett neues Chassis mit mehr Platz zwischen Vorderrädern (bei Vollgas) und Seitenschutz, neuen Positionen für die hintere Versteifungdsstrebe für verbesserte Flexeigenschaften des Chassis und abgeschrägten Vorderkanten. Das völlig neue Chassis-Design ist jetzt vollständig kompatibel zwischen dem XB8- und XB8E-„Plattformen“
- Die komplett neue Spoilerhalterung ist 40% leichter und hat einen extrem niedrigen Schwerpunkt. Mit deutlich weniger Gewicht hinter der Hinterachse, verbessert dies die Fahreigenschaften deutlich. Die komplett neue Konstruktion ermöglicht mehr Flexibilität und bietet neue, optimierte Spoilerpositionen
- Eine komplett neue hintere Verstrebung zwischen der Spoilerhalterung und der hinteren Chassisverstrebung verhindert einen Bruch des hinteren Getriebegehäuses
- geänderte hintere Getriebeabstützung mit optionalen Kohlefaserplatten
- neue Stoßdämpferbrücke mit zwei Befestigungsreihen für die hinteren Dämpfer
- Härtere hintere Querlenker für erhöhte Seitenstabilität und verbesserte Haltbarkeit unter heißen Bedingungen

World Champion Choice.
XRAY has been working very hard to make the XB8 platform more adaptable for tracks all around the world. The XB8 gives me the confidence to put the car where I want it – and do what I want it to do – on any track, any surface. It was amazing to work in person with Juraj and Martin Bayer at the factory, to express our needs for the car. The XRAY facility is truly amazing. I look forward to many successes with the XB8 in 2018.

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 XB8 is truly a masterpieces
Chassis.
With the chassis being one of the important components of the car, the all-new 2018 chassis features multiple improvements.
The rear brace mounting position on the chassis was moved rearwards to improve chassis flex and give increased traction.
The all-new 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.
Chassis.
With attention to the smallest details and a mandate to simplify servicing of the car, the all-new chassis features cross-platform compatibility to ensure you can use the same chassis either on the XB8 or XB8E.
The XB8 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. Non-essential material below the engine, fuel tank, and differential was removed to allow for the lowest possible center of gravity and appropriate chassis flex
Rear Wing Holder.
The rear wing holder is completely new and fully redesigned. It increases stability on high-speed tracks and has a super-slim, 1-piece design that has reduced weight and increased strength.
The complete wing mount is 40% lighter than the previous version, considerably reducing the weight behind the rear suspension as well significantly reducing the CG. The wing holder has been redesigned for 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 was completely reconstructed and now features an all-new 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.
Chassis Braces.
The all-new rear brace is shorter and the mounting position on the chassis is relocated for a new chassis flex point position. 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.
Shock Towers.
To increase the set-up possibilities of shock mounting adjustment, the all-new rear shock tower features two rows of shock positions to choose from.
HIGHER shock mounting holes: Increased traction, recommended for low-traction tracks
LOWER shock mounting holes: Increased stability, recommended for high-traction tracks
Aluminum towers are CNC-machined from premium Swiss 7075 T6 and then additionally black coated. The stiffer alu shock towers give better performance at high-traction tracks. Optional front graphite shock tower offers more flex to generate more traction, and is recommended for low-traction tracks.
Suspension Arms.
To improve performance and increase reliability in high-temperature conditions, new Hard arms are included in the kit. The long-version arms help to generate more traction.
Suspension arms – especially their flex, length, and position – are extremely important to the performance of the car, and as such various length and hardness of arms are optionally available.
LONG arms:
Increased traction, recommended for mid-size to large tracks.
SHORT arms:
Increased rotation, increased steering, recommended for short technical tracks.
To use short arms, optional suspension holders #353317 and #353325 must be used.
Ackermann.
To increase the reliability and strength of the ball-joints (especially in hard crashes), the 6.8mm steering ball joint were redesigned and reinforced.
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.
Pivot Balls.
To increase the reliability and free movement of suspension even in the extremely dusty conditions, the pivot ball cups are moulded from a new 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.
Gear Differential.
To improve the seal of the differentials and increase reliability (especially in long runs), the seal of the differentials was improved. The all-new diff O-rings operate very smoothly, while sealing the diff and preventing leakage even under high pressure.
The high-volume differentials ensure proper reliability and performance. They feature higher oil volume capacity cases, stronger diff pins, and large internal gears with more teeth for improved differential moment. The larger volume of the differential and the shape of the gear teeth reduce oil overheating.
Shocks.
To improve stability on bumpy tracks, the shock membrane is produced from a new softer material. The softer membranes ensure the shocks better absorb even the smallest bumps and improve stability on bumpy tracks.
Oversized big-bore shocks featuring 16.2mm I.D. shock bodies are externally threaded for 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.
Thick, robust shock shafts handle abusive racing conditions and big jumps. The 3.5mm thick shock shafts are precisely machined from special high-tensile steel, and afterwards are ground to a super-smooth finish to ensure smooth operation.
Drive Shafts.
To generate more rear traction in all track conditions, CVD drive shafts are used in the rear while universal drive shafts are used in the front to ensure stability and reduce vibration at maximum steering angle.
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.
Anti-Roll Bars.
To increase traction in all track conditions, the rear anti-roll bars were changed to 2.6mm.
Anti-roll bars are manufactured from spring steel material, are easily mounted to front & rear diff cases, and can easily be adjusted using adjustable linkages.
Anti-roll bar wires of different thicknesses are optionally available for fine-tuning.
Socket Head Cup Screws.
To increase lifespan and improve ease of servicing, new 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.
Body.
Long-term tested by Team XRAY, the new high-speed XB8 body is now included in the kit. The body give improved high-speed steering & stability while providing improved rotation in tight corners.
High-Performance.
With countless wins in multiple classes at local, regional, national, and international levels, XRAY XB8 is designed for highest competition racing and ready to win.
