Motorcycle Suspension Piston & Shaft Lock Nuts

Lock Nuts

All rebuildable motorbike front forks and rear shock absorbers need basic shared parts such as 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 for shim tuning, and rubber o-rings to keep oil and gas pressure sealed. These suspension components are used on either end of the bike when servicing or tuning.

Locknuts for Rebuildable Forks and Shocks

  • Secure damping pistons and shaft assemblies during vibration
  • Resist heat and oil where nylocs or loctite fail
  • Essential wear parts to replace at every rebuild
  • Compatible with OEM and specialist parts such as fujilok inserts

Use specialist parts like fujilok lock nut or OEM equivalents. See related items: Shock Shaft Top Locknuts, Damping Piston Locknuts, and Shock Shaft Bottom Lug Locknuts. For shims and valves see Valving Shims and our Shim Factor Calculator. Technical guidance: lock nuts and fasteners, suspension fluid weights table.

Recommended Pairings

Consider matching lock nuts with Suspension Tools for accurate rebuilds.
