Height and Quick Adjustment. The FOX IFP-QSR 13.5? raise the rear to increase ground clearance and stability in turns. The QSR (Quick Switch Rebound) selector allows you to adjust the rebound in 3 positions without tools: Soft (comfort), Medium (balance), and Hard (firm support).
The mono-tube architecture with internal floating piston (IFP) separates gas and oil, preventing foaming and maintaining consistent damping. The 6061-T6 Ø1.5? body with TIII hard anodizing and the Ø5/8? shaft with hard chrome provide thermal dissipation and low friction. Preload with guide marks and included wrench.
