Description

The Dynatrac ProRock 80 is an extremely robust, full-float rear axle assembly engineered for the most demanding off-road conditions. It's designed for Jeeps (Wrangler and Gladiator) running 40-44 inch tires, especially those with high-horsepower engines (V8 or higher) or very heavy builds (armored, loaded with gear) that tackle hardcore trails, off-road racing, or rock bouncing. It provides an exceptional margin of safety against breakage of ring gear, shafts, or housing in extreme situations.
