Motorcycle Shock Seal Case Lock Washers
Motorbike shocks use a damping shaft that slides inside the main shock absorber body. To keep all the oil and nitrogen pressure inside that casing there is a lower seal head assembly between the two.
Rear dampers have multiple defences in there - an oil seal held deep inside, a dust wiper on the outside, a rod bushing to keep it sliding concentrically, a rubber o-ring sealing the outer diameter and a rebound top out bumper facing inwards. That bump stop can be a rubber ring or a small steel coil spring, and it makes sure no damage happens if the shock piston bumps into the bottom case (like when you jump the bike).
The shock lower body sealing head is an oil lock, a metal guide disc inside keeping the flexible seals & rod bushing concentric around the damping rod. We have genuine factory KYB & Showa spacer holding shims.

To service the coilover end case you will need to remove the shock spring, so read our article on how to do it safely. It's a perfect opportunity to swap springs to the right spring rate for your weight too.
And once everything is rebuilt, keep in mind our suspension fluids section to refill the oil, and our regassing tools to gas it up.
