More height and better cornering, with FOX feel. The FOX IFP-R QSR 13.5? raise the rear end to increase ground clearance and delay footpeg scraping during dynamic riding. The mono-tube with internal floating piston (IFP) design separates gas and oil, preventing aeration and maintaining stable damping throughout your ride.
The QSR (Quick Switch Rebound) selector adjusts the rebound in 3 positions without tools: Soft for bump comfort, Medium for versatile use, and Hard for smooth sections at high speed. The 6061-T6 aluminum Ø2? body with Type III hard anodizing enhances thermal dissipation and wear resistance. The Ø5/8? hard-chromed, super-finished shaft reduces friction for superior initial sensitivity. The preload with guide marks makes setting the sag accurately easy.
