XRAY have introduced a new 2.5mm 7075-T6 aluminium chassis for the XB4. The chassis is CNC machined from 2.5mm high-quality Swiss 7075 T6 aluminum, anodised in black and strategically machined to make it as light as possible without affecting strength or rigidity and to achieve the desired flex characteristics.


It is designed and recommended for use at high-traction tracks without graphite front. The 2.5mm chassis increases cornering speed and overall stability. 

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 smooth chassis underside with no protruding screw heads.
