NL2121 is a genuine AxleTech locknut with a 3/4-10 thread, sold by Pro Gear and Transmission. It is listed in Meritor shock absorber bolt kits, front axle hardware and an air ride suspension bracket assembly.
A locknut is built to resist backing off under vibration and load, so the joint it clamps keeps its tension between service intervals. One that spins on freely by hand has lost its bite and should be replaced. Call us to confirm proper fit for your application.
