Which Fox Forks Does the GRIP Damper Seal Kit Fit?

The FOX Cartridge Seal Kit for GRIP Damper Forks is a genuine OEM rebuild solution covering the 32, 34, 36, and 40 series Fox forks from 2019 and newer. The GRIP damper cartridge is Fox's closed-cartridge system designed for consistent, adjustable damping on trail and enduro builds, and this seal kit includes everything needed to restore it to factory performance. Using OEM-spec seals ensures the correct material and tolerances for Fox's cartridge system, preventing the oil bypass and damping inconsistency that worn seals cause over time and hard use.

Fox part number 803-01-320 covers a wide range of GRIP-equipped forks, making this kit a shop staple for anyone maintaining multiple Fox builds. A proper cartridge rebuild refreshes both compression and rebound damping feel, eliminating the vague or blown-through sensation that signals seal wear. This kit is compatible with 2019 and newer 32, 34, 36, and 40 models equipped with the GRIP damper, not GRIP2. If you are unsure which damper your fork has, check the lower leg decal or Fox's online compatibility tool before ordering. Best for mechanically confident riders and home shop builders maintaining Fox suspension on trail, enduro, or cross-country bikes.
