The XRAY 302144-C Composite Upper Arm offers a targeted upgrade for XRAY X4 cars, improving tyre contact and suspension robustness. It fits the front left and rear right locations to help deliver more consistent lap times.
The part is designed from a composite material that provides controlled flex, which helps the tyre maintain contact through transitions and under acceleration, enhancing corner speed and exit stability.
Built to handle the stresses of competitive running, the arm shields the inner shock area and reduces radial play, which contributes to steadier steering and less component movement after impacts.
The XRAY 302144-C is manufactured for correct fitment on XRAY X4 chassis in the specified front left and rear right positions, simplifying replacement and setup for X4 owners.
