Motorcycle Shock Piston Retaining Locknut

Teknik Shock Shaft Lock Nuts

Shock Shaft Lock Nuts

Secure the piston assembly on your rear shock with specialised lock nuts made for constantly vibrating, high‑temperature and oil‑soaked damper shafts.

Lock nuts for securing piston to damper rod

Prevent loosening under constant vibration on coilovers and shocks
Compatible with piston o-rings, bushes and PTFE sealing bands
Use OEM or FujiLok style locking inserts where Loctite or nylocs fail
Essential for rebuilds, revalving and performance damping work

Recommended Pairings

Consider matching these lock nuts with Suspension Tools for safe assembly and torque control.

These lock nuts attach the piston and its valving shims to the shock shaft. You cannot use a normal nut, Loctite or nyloc due to heat and oil – opt for a fujilok lock nut or OEM equivalent. Read our nuts & bolts tech article and use tools like the shim equivalence calculator when revalving. Watch Teknik's Nick rebuild and revalve a shock for practical guidance.
