Suspension Wave & Delta Shim Collection - Sold in Packs of 10

All rebuildable suspensions need shims & washers - and Teknik has the largest collection - more than 2 million in stock. Our range isn't just standard flake valves 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.

Unlike a flat steel disc valving shim that flexes from oil pressure, absorbing energy & creating damping force, these specialist shims give different tuning options.
A delta shim is basically a normal round shim cut into a triangle shape, the cutouts meaning that oil flows around the edges, giving softer initial damping.
A wave washer is bent to act a bit like a leaf spring, spacing different parts of the shim stack apart till there is enough force in the damper to flatten it.

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.

If you are a bike workshop or a DIY suspension tuner you should stock up on these basic 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.
