XRAY 343133-H Rear Upper Arm Hard Composite RX8  [XR-343133-H]

Durable Hard Composite Rear Arm for RX8

The XRAY 343133-H Rear Upper Suspension Arm uses a tough composite formulation to give RX8 cars increased longevity and more consistent handling. The hard version reduces unwanted flex so the rear end reacts predictably through corners on technical tracks.

Precision Build for Consistent Lines

This longer arm layout helps spread impact forces and reduces concentrated wear on suspension points, which supports stable toe and camber under load. Racers will notice steadier throttle transition and improved rear grip feel.

Installation and Compatibility Notes

Built to mate with RX8 2025 chassis geometry, the arm fits into existing mounts and requires minimal setup adjustment. It is a straightforward swap for tuners wanting a firmer rear setup without altering major components.
