Automotive Suspension Valving Shims & Washers

Teknik Shims

All rebuildable suspensions need shims & washers - and Teknik has the largest collection - more than 2 million in stock. Our range isn't just standard valving shims either: 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 - one 0.30mm shim is NOT the same as two 0.15mm shims.

There are other shared parts found in both front forks & rear shocks; 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 suspensions need these when servicing or tuning, and you can find them in our fork locknuts & bushes and shock absorber locknuts & bushes.
