FOX 40 FIT Cartridge Seal Kit 803-00-150 + RacingBros Wiper Seals & Service Oils

Complete service kit for selected older FOX 40 suspension forks with a FIT damping cartridge. This set combines the FOX cartridge seal kit 803-00-150 with high-quality RacingBros wiper seals and the required oils for servicing both the damping cartridge and the lower legs.

The FOX cartridge seal kit is designed for a complete rebuild of the early FOX 40 FIT damping cartridge. It includes the relevant internal cartridge seals, including cartridge O-rings, damper bladder, shaft U-cup seal, external glide rings and crush washers.

The included RacingBros wiper seals replace the original dust wipers. They help protect the stanchions from dirt and moisture while retaining lubrication inside the fork.
