Fox - 1991-2017 Harley-Davidson Dyna - QS3 QSR (Piggyback)

The new FOX QS3-QSR rear shocks have been redesigned to include both three-position compression and rebound Quick Switches. The Quick Switch compression (QS3) three-position adjustments on the piggyback reservoirs allow you to select between three specific settings: maximum comfort, extra support during hard acceleration, or most responsive and precise handling. The main piston valving has been reconfigured and extensively ride tested in a full range of conditions to work in harmony with the new three-position Quick Switch Rebound (QSR) settings. Three distinct settings make it easy to dial in the correct rebound for different riding situations: comfort on bumpy backroads, “any road” balance of control and comfort, and a “glued to the asphalt” feeling on smooth twisty roads. In addition, external piggyback reservoirs house internal floating pistons to separate the nitrogen gas from the shock oil, meaning the QS3-QSR shocks will maintain damping control no matter how long you ride. FOX’s new QS3-QSR compression and rebound adjustable design—combined with vehicle specific damping and linear spring rates—gives you the ability to quickly adapt to any riding situation.

Combine the FOX STREET PERFORMANCE QS3-QSR REAR SHOCK SET with the new FOX GRIP STREET PERFORMANCE FORK CARTRIDGE KIT FOR HARLEY DYNA to get the best possible ride quality with the ultimate in adjustability for comfort and control.
