For those running the XRAY X4, the 302133-M medium carbon-fiber fusion upper arm provides a stiffer option for the front and rear left suspension while helping maintain precise wheel control. It works well as a targeted upgrade for track-focused setups.
The XRAY 302133-M uses carbon fibre to reduce unwanted flex while keeping weight under control. The fusion manufacturing approach helps preserve suspension geometry through demanding sessions.
Specifically produced to match XRAY X4 mounting points, this upper arm installs without reworking your chassis. Fit it to replace ageing parts or to firm up handling for improved consistency.
The XRAY 302133-M is a practical choice for competitive hobbyists seeking steadier steering and better control at speed.
