The FOX IFP-QSR rear shock is made for controlled solo or comfortable two-up riding, using an internal floating piston to maintain damping control to separate the nitrogen gas from the shock oil. The internal tune to match the quick switch rebound adjusters, allow you to quickly tune the rebound rate to balance the road conditions and your spring preload while maintaining a planted feel on the road. We engineer the IFP-QSR shocks with linear spring rates, vehicle-specific damping and 3 position quick adjust rebound to accommodate your ideal spring preload, either very soft or very firm. Soak up the bumps with confidence and go the long route, every time. Looking for the FOX full bike solution? Start with our IFP-QSR rear shocks and add our new GRIP-Street Performance fork cartridge kit to balance performance and extend your ride. Solo, loaded or two-up riding will never be the same.
