Motorcycle Shock Sealing Rubber O-Rings

All rebuildable motorbike front forks & rear shock absorbers need some basic shared parts - fasteners like locknuts to hold damping pistons to base towers, teflon lined shaft collars or acetal rod bushes to hold sliding tubes concentric without friction, mid-speed valve (or refill / non-return) springs to help tune your shim stack, rubber o-rings to keep oil & gas pressure sealed. These suspension components can be used on either end of the bike when you are servicing or tuning.

These shock o-rings are listed in their categories separately too; there are obvious ones like Lower Seal Case O-Rings & the fluid separating Damping Piston O-Rings, but you may not have thought of the tiny ones inside Shock Shafts, or keeping dust outside of the Top Mounting Bearings.
There's small o-rings in both Comp Adjuster Parts as well as Reb Adjuster Parts, plus you'll find little ones sealing the Shock Body Service Port & Bladder Cap Air Port.

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.
