Dynatrac ProRock 80 Rear Axle Kit w/ARB Locker

The ProRock60 has long been the benchmark to which axles have been measured. When looking for the King of axles you had to look no further than the now-legendary ProRock60. As the off-road world has evolved, Dynatrac has raised the bar again with the introduction of the new ProRock80!

The lightest axle in its class, the ProRock80 has all the beef you’ll need in your JK to handle the largest tires with the hottest motor. Designed to handle just about anything you can throw at it, the ProRock80 has the strength to get you there and back. The ProRock80 is based off of the massive Dana 80. We took the best features of the Dana 80, added in the best features of our ProRock design and ended up with an axle that can handle the toughest terrain.

Our ProRock80 housing is designed for real-world conditions with real-world abuse. A low pinion design, the ProRock80 is ultra sleek but incredibly rigid. With an 11.25” ring gear and a 2” diameter pinion, the ProRock80 has unequaled strength in the 4x4 world. Add in 40 spline 4340 full floating axle shafts and you have an assembly that can handle huge tires, a massive rig and a heavy right foot.
