Description

The Dynatrac ProRock 80 is an extremely robust full-float rear axle designed for the most demanding off-road conditions, including competitions and severe trails. It provides an extra margin of strength when a Dana 60 axle is insufficient. It's ideal for Wranglers or Gladiators with high-horsepower engines or heavy modifications, tackling hardcore off-roading, off-road racing, or rock bouncing. It offers maximum confidence, ensuring the ring gear, shafts, and housing remain intact even under extreme stress. While primarily for off-road, it is still drivable on the street, though it adds rotational mass, slightly affecting acceleration and MPG. It is marketed as the strongest, highest ground-clearance axle in its class.
