FOX IFP-QSR Rear Shocks for Harley Dyna 1991-2017

FOX IFP-QSR Rear Shocks for Harley Dyna — Street Performance (Standard: Rider up to 240 lb)

Experience improved comfort and precise control with FOX IFP-QSR rear shocks for Harley Dyna. The internal floating piston (IFP) separates nitrogen gas from the shock oil to maintain consistent damping throughout long rides, while the QSR 3-position quick-switch rebound lets you dial in the ideal response for bumpy backroads, mixed surface “any road” riding, or a planted “glued to the asphalt” feel on smooth twisties.

• QSR: 3-position quick switch rebound adjustment — easy on-the-fly tuning for different road conditions
• Spring preload setting guide marks for fast, repeatable adjustments
