Dura Blue 20-1651 3-Piece Posi Lock Nut

It’s not uncommon for the axle nuts on an ATV to work themselves loose. When this happens, serious damage can occur to both the machine and rider. Dura Blue has developed their 3 Piece Posi Lock Nut to combat this problem and keep you from having to constantly retighten your axle nut. The design of the Posi Lock Nut incorporates a threaded inner ring, an outer threaded clamp locking ring, and a snap ring so your axle nut is not susceptible to vibrations or harmonics that would otherwise cause it to work loose. The Posi Lock is used in a similar way as your stock axle nut and requires no modification to your Dura Blue axle. In fact, it has fewer pieces than most stock nuts for simple and more effective usage.
