The best-of-the-best technology FOX has to offer. 

The award-winning 36 gets a huge performance boost with the new FIT GRIP2 4-way adjustable damper. Equipped with the patent-pending Variable Valve Control (VVC) high- and low-speed rebound adjuster, improved compression damping and less friction overall, the 2019 36 offers a new level of performance and adjustability that matches the X2 shocks.
