Motorcycle Suspension Shaft Slide Collars

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 & gas pressure sealed from each other. Motorbike front fork legs & rear shock absorbers both need these when servicing or tuning, and here is where you'll find them.

While a bigger main Shock Shaft Bush needs fancy friction-less coatings on the inner diameter to constantly slide, some pushrods don't get moved often, so only need a basic steel ring to stay aligned. Inside the middle of the damper rod in adjustable shocks you'll often find these little metal collars keeping the adjuster push rods centred.
