Motorcycle Suspension Shock Lock Nuts / Bushes / O-Rings

Suspension Lock Nuts & Bushes

Essential wear parts for rebuildable motorcycle front forks and rear shock absorbers. Find locknuts, teflon lined shaft collars, acetal rod bushes, tiny mid-speed valve (also called refill or non-return) springs, rubber o-rings and associated fasteners needed to hold damping pistons, seal oil and gas, and keep sliding tubes concentric with minimal friction.

Service and tuning essentials for forks and shocks

  • Secure damping pistons to base towers with correct locknuts
  • Maintain concentric sliding action with teflon lined collars and acetal rod bushes
  • Fine-tune mid-speed response with refill/non-return springs and shims
  • Prevent leaks and pressure loss using quality rubber o-rings and seals

Recommended Pairings

Consider matching these parts with Suspension Tools for accurate rebuilds. For damping shims and washers see our Valving Shims section and use the Shim Equivalence Calculator. Technical notes on fasteners and oils are available: lock nuts and fasteners and suspension fluid weights table.
