💡 [RECOMMENDED PAIRING]:
If your original sprocket nut is worn or rusted, it’s also a good idea to replace it. A clean nut and a new washer guarantee maximum safety. View Front Sprocket Nut Here.

🔧 Install Tips

Torque to Spec: Use a torque wrench! Tighten the nut to the factory specification (check your manual for Nm/ft-lb settings). Don’t guess the torque.
Lock it Down: After torquing the nut, use a flathead screwdriver and a small hammer to carefully bend one edge of the new washer over a flat side of the nut.
Cleanliness is Key: Clean the gearbox shaft threads of old grease and dirt for an accurate torque reading.
