Motorcycle Shock Damping Piston Parts

 

Your rear shock absorber has a complex thick metal disc with machined passages flowing between both flat sides, and to make sure the suspension fluid can only flow through these holes, a rubber o-ring and a teflon coated bush (or a soft PTFE band) seal around the outer diameter.

Stacked on both sides of this piston are the valving shims, a collection of thin steel washers that flex when pushed by the oil pressure. They come in a huge range of diameters and thicknesses, and are arranged in a very specific order to create the right damping characteristics, with the compression valve stack on one side, and rebound stack on the other. The piston and it's shim stacks are then attached to the end of the shock shaft using a locknut.
