Description
Stock shock seals degrade under extreme temperatures and repeated compression cycles, compromising your suspension’s ability to maintain consistent damping performance. The FACTORY CONNECTION FCS-18U upgrades your seals with a more compliant rubber compound that flexes reliably across temperature swings while resisting the wear that stock seals succumb to. If you’re pushing your suspension hard—whether on track or in demanding terrain—this seal replacement extends service life and preserves the damping characteristics your shocks were tuned to deliver.
