PF Relent Billet Swing Arm - FXR (Engineer Certified)

⏳ Pre-Order Notice - This item is made to order.
Estimated lead time: 4–6 weeks before shipment.

Zero flex. Sharp handling. Built for performance.

Designed and machined by Project Faster in Canada.

The PF Relent FXR Swingarm is engineered to eliminate flex, sharpen handling, and bring modern performance to the FXR chassis. Precision-machined in-house from 6061 aerospace-grade aluminum—not a modified OEM part, but a ground-up performance component designed for strength, alignment accuracy, and high-load stability.

The engineered arc profile increases structural integrity where load transfer is highest, improving rear-end stability under throttle and maintaining consistent tracking at speed. Titanium axle and full titanium hardware package reduce unsprung weight while increasing strength and corrosion resistance. The PF hidden adjuster system keeps the rear profile clean while delivering precise, repeatable wheel alignment.

Built for riders who demand precision, stability, and durability—whether carving canyons or putting serious power to the pavement.
