XRAY 302181-H X4 Carbon-Fiber Fusion Front Lower Arm Hard Left - Race Spec  [XR-302181-H]

Precision Front Lower Arm for X4 Racers

The XRAY 302181-H X4 CFF Carbon Fiber Fusion Front Lower Arm is a race-minded left-side component created to stabilise front-end behaviour. By fusing a carbon fibre internal plate with a composite exterior, XRAY achieves a durable but lightweight arm that helps preserve steering geometry under corner loads.

Best Suited to Carpet and Sticky Asphalt

This hard-rated arm is optimised for carpet and other sticky surfaces. The stiffness comes from the inner carbon plate thickness, while the composite shell controls flex and rebound characteristics. The combined effect is improved mid-corner stability and crisper turn-in compared with standard M arms.

High-Quality Graphite and Composite Finish

Manufactured from premium graphite and composite, the XRAY CFF arm remains compact to reduce rotating and unsprung mass. Its harder composition delivers consistent responses so drivers can focus on fine-tuning suspension and steering settings.
