Motorcycle Shock Seal Case Assembly

Teknik Shock Seal Case Assembly

Shock Seal Case Assembly

Motorbike shocks use a damping shaft that slides inside the main shock absorber body. To keep oil and nitrogen pressure inside the casing there is a lower seal head assembly between the two. We stock pre-assembled shock lower body cases for factory motorcycle suspensions like KYB & Showa and reputable aftermarket options such as SKF and All Balls.

Seals and assemblies that retain pressure and protect internals

  • Seal oil and nitrogen pressure in the lower shock body
  • Dust wipers, oil seals, rod bushings and rubber o-rings to prevent contamination
  • Rebound top out bump stops or small coil springs protect the piston and bottom case
  • Pre-assembled units save time over fitting individual washers, dirt seals and bushes

Recommended Pairings

Consider matching with Suspension Tools and read guidance on how to remove the shock spring or choose the right spring rate. Refill with suspension fluids and use regassing tools after rebuild.
