Motorcycle Shock Shaft & Piston Lock Nuts

Teknik Shock Piston Retaining Nuts

Shock Piston Retaining Nuts

Right in the centre of your motorbike's coilover is the main damping shaft. These top locknuts secure the piston inside the shock absorber body and prevent the valving piston from walking under vibration, heat and oil exposure. You need a specialist lock nut — such as a fujilok lock nut or OEM equivalent — not a standard nut, nyloc or loctite. Read our nuts & bolts tech article for fitting tips.

Secure the valving piston assembly

  • Locks the valving piston assembly in place against vibration
  • Compatible with compression & rebound shim stacks and piston groups
  • Resists heat and oil where nylocs or loctite fail
  • Used when rebuilding or revalving rebuildable dampers

Recommended Pairings

Consider matching these nuts with our Suspension Tools and review piston parts like Shock Damping Piston Group and compression & rebound shim stacks.
