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 are often found in the Cartridge Seal Cases with a friction-less coating on the inside to slide easily over the main cartridge rod, aligned in the middle of the fork legs. They can wear away the coating & start grinding away from side loads - so this bush prevents parts scraping & stops leaks.
These are not the big Fork Tubes Inner Slide Bush or it's counterpart the Outer Guide Bush - which are also available as an Inner & Outer Kit. We sell the bushes found on the outside of your Spring Perches & compression adjuster Free Pistons separately too.

Other shared components that are in both forks and shocks are shims & washers - but Teknik Motorsport have so many that we have our own Valving Shims section - including complete bulk kits, ring shims, check shims, cup washers and valve stop washers. If you need to swap damping shims please see our Shim Factor Calculator - a 0.30mm shim is NOT the same as two 0.15mm shims.

If you are a bike workshop or a DIY suspension tuner you should stock up on these essential wear parts - they are in everything and should be replaced every rebuild. We also have technical articles that can give you an edge: learn more about those lock nuts and fasteners or become an expert on oils with our suspension fluid weights table.
