Motorcycle Shock Piston & Seals Assembly

Your rear shock absorber has a complex internal 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.

These OEM KYB & Showa main piston assemblies include the rubber o-rings & metal bushing rings or outer gapless bands already installed - we sell them individually too. The valving shims are then stacked on both sides, a collection of thin steel washers that flex when pushed by the oil pressure. They come in a huge range of diameters & thicknesses and are arranged in a very specific order with valve stop washers to create the right damping characteristics, with compression stack on one side, and rebound on the other. The piston & stacks are then locked to the end of the shock shaft using a locknut.
