Motorcycle Suspension Rod Guide Bushes

All rebuildable suspensions need some basic shared parts - fasteners such as locknuts to hold damping pistons to base towers, teflon lined shaft collars or acetal rod bushes to hold sliding tubes concentric without too much friction, tiny mid-speed valve (also called refill or non-return) springs to help tune your shim stack, rubber o-rings to keep oil and gas pressure sealed from each other. Motorbike front fork & rear shock absorbers both need these when servicing or tuning, and here is where you'll find them.

These steel or brass ring bushings have a friction-less coating on the inner diameter to slide easily over the main shock shaft, keeping it aligned inside the middle of the damper, so can also be found in our Seal Case Bushing section. With poor lubrication they can wear away the coating and start grinding away from side loads. Bad link bearings make it worse. If they go oval enough that the seals leak & the piston starts scraping the shock body bore, your whole coilover is toast, so changing this bush is cheap insurance.
