The XRAY 303172 Aluminum Rear Suspension Arm is machined from Swiss 7075 T6 aluminum to give a firmer rear end on high-traction circuits and carpet tracks. Swapping in this arm reduces unwanted flex compared to stock composite graphite parts, helping drivers find cleaner cornering lines and steadier mid-corner behavior.
This single 1-hole design provides an optimized shock mounting point for predictable handling at speed. Built-in anti-roll bar mounts help lower body roll and stabilise the chassis during rapid direction changes.
The arm is made to drop into compatible setups with minimal fuss and usually uses the same mounting hardware as the original arm. You can buy these arms individually or as a matched set to suit your tuning needs.
