Motorcycle Shock Seal Case Parts

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 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).

We sell complete assembled replacement seal cases for most suspensions - but also bare heads, washers & individual components so you can tune & service your coilover how you want.

To get at the seal 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.

But if you're not confident you can manage it yourself, Teknik offer a 12 month warranty on shock oil seals we've installed.
