XRay XB4 20 Aluminium Chassis - Swiss 7075 T6 (2mm)

The XRay XB4 20 Aluminium Chassis (XR361107) delivers a refined balance of stability, flex and durability. Redesigned with a longer layout, it enhances the car’s composure on track while maintaining responsive handling. Precision CNC-machined from high-quality 2mm Swiss 7075‑T6 aluminium, the chassis is strategically pocketed in low-stress areas to reduce weight without compromising rigidity.

Engineered to accommodate a lower motor mount, the design allows the motor to sit lower in the chassis, supporting improved cornering speed and overall stability. Weight distribution, width and length have been considered throughout to positively influence handling. A tough black coating increases lifespan, and all underside screw holes are fully countersunk for a smooth, snag-free chassis bottom.
