ProX Fork Seal & Wiper Kit (48mm x 58mm x 10mm) 40.S485810 - Suzuki RM-Z250 / RM-Z450 2004-2015

Product Description

Restore smooth suspension action and leak-free performance to your front end with the ProX Fork Seal & Wiper Kit 40.S485810. Engineered to replace worn or weeping factory seals, this complete kit features genuine NOK replacement oil seals and dust wipers manufactured to exact original equipment tolerances. Worn fork seals allow oil to escape onto your front brake rotor and permit dirt to migrate into the fork bushings—installing fresh seals ensures your front suspension stays plush and fully pressurized.

Designed specifically for 48mm front fork assemblies with a 58mm outer diameter and 10mm thickness, the ProX 40.S485810 kit delivers low-friction performance while maintaining a resilient barrier against fine roost and water contamination. Whether you are performing routine suspension maintenance or rebuilding your front legs after a hard season of racing, ProX provides the sealing integrity and durability needed for demanding motocross conditions.

Frequently Asked Questions

Q: Does one kit service both front fork legs?
A: Yes, the ProX 40.S485810 kit includes two fork oil seals and two dust wipers, providing everything needed to complete both left and right fork legs.

Q: Are these genuine NOK seals?
A: Yes, ProX sources genuine NOK seals for their fork seal kits to deliver original equipment sealing performance and minimal sliding friction.

Expert Pro-Tip: When installing new fork oil seals over the top of the chrome fork stanchion, always wrap the sharp edge of the bushing groove and snap ring recess with thin electrical tape or seal-bullet plastic. Generously coat the inner seal lips with clean suspension grease before sliding them into position to prevent tearing or nicking the rubber seal lips on sharp metal edges.
