Motorcycle Suspension Piston & Shaft Lock Nuts

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.

You can't use normal nuts for many shocks due to the constant vibration, you can't use loctite or nylocs either, due to the heat & oil. You need a special fujilok lock nut (or OEM equivalent) with a locking stainless steel spring insert. These locknuts are listed in their categories separately too; you can find the Shock Shaft Top Locknuts and the same parts are also in the Damping Piston Locknuts. There are also the Shock Shaft Bottom Lug Locknuts which bolt up the clevis or yoke.
