It fits securely between your engine’s front sprocket and crankshaft, physically locking the sprocket nut in place to prevent loosening during operation. This prevents unwanted movement or slippage of your sprocket, protecting your chain, gearbox, and potentially avoiding dangerous riding conditions.

🔧 Install Tips

  • Clean Threads: Clean the sprocket hub and crankshaft threads to remove any dirt or old threadlocker residue before installation.
  • Torque Specs: Use the manufacturer’s recommended torque settings when tightening the sprocket nut. Overtightening can snap the bolt; under-tightening is a safety hazard.
  • Engage Lock: Ensure the washer’s locking tab is physically bent over one of the flats of the tightened nut to prevent rotation.
  • Peace of Mind: Using a fresh, genuine OEM part guarantees fit and peace of mind on every ride. Don’t compromise on safety.
