Automotive Suspension Valving Check Shims

Check Shims

All rebuildable suspensions need shims and washers, and Teknik stocks more than 2 million parts including bulk kits, ring shims, check shims, cup washers and valve stop washers. Check shims are thicker non-return valve support washers used in shim stacks to limit thin valve shim travel and create predictable damping behaviour in forks and shocks. If you need to swap damping shims please see our Shim Factor Calculator.

Purpose of Check Shims in Valving

  • Limit thin valve shim flex to define high-speed and low-speed control
  • Support non-return valves and improve rebound/damping reliability
  • Essential wear parts for forks and rear shocks during every rebuild
  • Compatible with cup washers and valve stop washers for tailored valving

Recommended Pairings

Consider matching with Suspension Tools for accurate assembly and with cup washers or valve stop washers as required.
