XRAY 302133-M Carbon-Fibre Fusion Upper Arm for X4  [XR-302133-M]

Tune your X4 response with the XRAY 302133-M component

The 302133-M medium carbon-fiber fusion upper arm is aimed at RC users wanting firmer, more predictable behaviour from the XRAY X4 front and rear left suspension. It suits racers and garage tuners who prioritise consistent part performance.

Stiff yet lightweight carbon-fibre design

Built from carbon fiber, the XRAY 302133-M balances strength and reduced mass to limit unwanted flex. The fusion build helps the arm hold alignment under load so steering inputs remain precise.

Made to match X4 assembly points

Precision cut to fit the XRAY X4 series, this upper arm integrates directly with stock hardware and layout. Fit it as a service replacement or to stiffen an existing setup for more repeatable handling.

A solid upgrade for track-focused hobbyists, the XRAY 302133-M helps deliver steadier steering and improved chassis control.
