Automotive Suspension Damping Valve Stop Washers

All rebuildable suspensions need shims & washers - and Teknik has the largest collection - more than 2 million in stock. Our range isn't just standard flake valves either: 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 - one 0.30mm shim is NOT the same as two 0.15mm shims.

Valving shims are thin and designed to flex from oil pressure, absorbing energy and creating damping force. But you don't want them to flex forever, or you wouldn't generate enough damping for big hits. So shim stacks use these much thicker locknut support / valve spacer washers to limit the distance that the thinner valve shims can flex - depending on the application they act like a cup washer or to the very similar looking check shim.
