Fox 34 Grip X Damper Top Cap The Climb Switch You Actually Need When your 34 is running an older FIT4 or FIT RC2 damper, you're leaving performance on the table. The Grip X Top Cap Assembly is the service and replacement piece that keeps your 2025 34-series fork running the way it was designed to. The Grip X damper platform sits between the Grip X2 and Grip SL in Fox's lineup, aimed squarely at trail and all-mountain riding where you want real adjustability without the weight or complexity of a gravity-spec cartridge. One of its standout features is the HSC dial's Firm mode: crank it all the way clockwise to the final click and both high and low-speed compression close simultaneously, giving you a solid platform for climbing or pavement stretches. Back it off before you drop in and the fork is back in business. If your 34 needs this cap, this is the correct part to keep it dialed.
