FOX IFP-QSR Rear Shock for Harley M8 Softail 2018+

FOX IFP-QSR Rear Shock for Harley Softail MY20+

Experience ultimate comfort and control with the FOX IFP-QSR rear shock. Featuring an Internal Floating Piston (IFP) to separate nitrogen gas from the shock oil, this gas-charged mono-tube shock maintains consistent damping no matter how long you ride. The QSR 3-position quick-switch rebound gives three distinct settings—comfort for bumpy backroads, an “any road” balance of control and comfort, and a “glued to the asphalt” feel for smooth twisty roads—so you can quickly dial the ride to match conditions.

Designed and tuned specifically for Softail MY20+ models, the FOX IFP-QSR delivers improved ride quality, precise control, and long-term serviceability. Pair it with the FOX GRIP Street Performance Fork Cartridge Kit for Harley Softail to achieve the best possible balance of comfort and handling.
