Based on the ultra-successful XB8 platform, 
XRAY proudly presents the 2015-spec XB8 which 
incorporates the latest improvements and refinements. Dipl. Eng. Juraj Hudy, XRAY XB8 platform designer: 


"During the entire year we have collected feedback, comments, improvements, and suggestions not only from team drivers but also from customers around the globe. Happily, the vast majority of feedback and comments were very positive, and as such we had a very challenging task with the 2015 improvements as there was not much to improve!  


The 2015 XB8 raises the bar even higher in this ultra-competitive, innovation-filled class. The new XB8

Chassis.

Newly-redesigned chassis has a more rear flex which helps to generate more traction. 

The chassis is CNC-machined from 3mm high-quality Swiss 7075 T6 aluminum, which is 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. 

Weight distribution, chassis width, and chassis length have a key influence on the handling of the car. All of these features were incorporated into the design of the chassis. 

All screw holes on the bottom of the chassis are countersunk, allowing for a very smooth chassis underside with no protruding screw heads. 

Shock Towers.

To increase the reliability and lifespan as well as improve performance, the graphite shock towers are replaced with aluminum towers that are CNC machined from premium Swiss 7075 T6 and then additionally coated. The stiffer alu shock towers, together with new shock positions, improve the performance at high-traction tracks. 

Optional graphite shock towers offer more flex and generate more traction, and are recommended for low-traction tracks. 

Diff Outdrive Adapters.

The longer diff outdrive adapters ensure that the drive shafts will not fall out 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 from the outer part of the outdrives 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. 

The outdrives are hardened using HUDY’s own special hardening process to provide extended life time and reliability.

Shock Pistons.

New 6, 8 and 10-hole pistons have a new improved design with a better-sealing fit in the shock bodies, which gives improved landings and makes the car more stable.

Reinforced Steering Ball-Joints.

Air Filter.

Shock Springs.

New shock springs improve the stability of the car and make it easier to drive. 

XB8 springs have been specifically designed to complement the big-bore shocks. 

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. 

There are two types of springs offered:

Pivot Balls.

The front upper pivot balls were reinforced to improve front suspension reliability in serious crashes. 

XRAY Multi-Flex™.

The invention of XRAY Multi-Flex Technology™ has resulted in some of the most significant milestones in RC model car development in the last decade. This innovation has not only resulted in awards and accolades, but has proven to be a distinct competitive advantage at tracks worldwide, helping XRAY cars dominate races at local and national levels. 

XRAY off-road cars were the world’s first off-road cars incorporating Multi-Flex™ adjustment technology, which allows tuning of chassis flex for different track conditions. 

It doesn’t matter if the track has low, medium or super-high traction, you can adjust chassis flex to suit track conditions in a matter of seconds… and then re-adjust flex easily if conditions change. It has never been so easy to professionally set up flex. Yet another smart innovation from XRAY.
