Dirt Bike Fork Seals, Springs and Suspension Parts
Suspension makes or breaks how a dirt bike rides. Worn fork seals leak oil onto your brakes, tired bushings and linkage bearings make the bike feel vague, and springs set up for the wrong rider weight make the bike bottom out or ride harsh. Keeping your suspension fresh is one of the best upgrades you can make.
We carry fork seals from SKF and Leak Proof Seals, bushings and fork rebuild kits, Race Tech springs and Gold Valves, KYB service parts, and linkage and shock bearing kits from ProX and Factory Links. Fresh linkage bearings alone can change how the rear end feels.
Leaking fork seals can contaminate your pads, so check dirt bike brakes after a seal job, and grab fresh wheel bearings while the front end is apart. Fork guards are in accessories.
Suspension parts are specific to your fork, shock and model, and spring rates depend on rider weight. Check fitment before ordering, and if you need help picking springs, send us your weight and bike details.
