Description
Fork seals wear out—it’s not a question of if, but when. Worn seals compromise suspension performance, allow hydraulic fluid to leak onto your brakes, and can damage fork internals if left unchecked. The PROX Fork Seal/Wiper Kit gives you genuine NOK replacement seals and wipers to restore your fork’s integrity and maintain consistent damping performance lap after lap.
This is a bolt-on replacement set designed for 48 mm ID forks. Whether you’re running a dirt bike, dual-sport, or lightweight motorcycle, keeping fresh seals in your suspension is non-negotiable maintenance—especially if you ride hard or compete regularly.
