The XRAY 302144-C Composite Upper Arm is an effective upgrade for the XRAY X4 lineup, built to increase traction and strengthen suspension components. Intended for the front left and rear right positions, it is a practical choice for racers and club drivers who want more predictable handling.
The composite construction delivers a balance of flexibility and toughness, which improves forward traction and side bite. This helps the car maintain grip during acceleration and cornering across a variety of track surfaces.
Manufactured for rugged use, the upper arm resists wear and impact while keeping necessary clearance around the inner shock location. Its geometry reduces unwanted play for crisper steering response after heavy landings or impacts.
The XRAY 302144-C is shaped to fit the XRAY X4 models at the front left and rear right mounting points, allowing straightforward installation and reliable compatibility with X4-series setups.
