Motorcycle Shock Seal Case Lock Washers

Teknik Shock Seal Head Washer

Shock Seal Head Washer

Motorbike shocks use a damping shaft that slides inside the main shock absorber body. To keep oil and nitrogen pressure sealed there is a lower seal head assembly between the two. Rear dampers include an oil seal, an external dust wiper, a rod bushing for concentric sliding, a rubber o-ring sealing the outer diameter and a rebound top out bumper; that bump stop can be a rubber ring or a small steel coil spring. The shock lower body sealing head acts as an oil lock with a metal guide disc keeping flexible seals and the rod bushing concentric. We stock genuine factory KYB & Showa spacer holding shims. To service the coilover end case you may need to remove the shock spring; consider swapping to the right spring rate, use our suspension fluids to refill, and our regassing tools to gas the shock.

Lower seal head purpose and protection

  • Retains oil and nitrogen pressure to preserve damping performance
  • Prevents contamination with dust wipers and rod bushings for longevity
  • Protects the piston and case from bottoming via rebound top out bumpers
  • Provides an oil lock and metal guide disc to keep seals concentric

Recommended Pairings

Consider matching seal head service with Suspension Tools for safe spring removal and regassing.
