Fox's innovate Dual Speed Compression (DSC) adjusters allow for further adjustment of both high- and low-speed compression. Each Fox shock is valved for its application to get compression and rebound tuning just right. The Factory Race Series shocks will enable your 4Runner, GX or FJ Cruiser to take on tough terrain in comfort and at a faster pace and will transform the ride quality and capability of your 4Runner , GX or FJ Cruiser in any terrain.
