Description

The Dynatrac ProRock 44™ for the Jeep Wrangler JL and Jeep Gladiator JT is a direct replacement front axle housing with significantly stronger axle tubes and end forgings. It eliminates the Front-Axle Disconnect (FAD), allowing for tires up to 38-inches tall. Available in two widths to match stock axle widths of Sport/Sahara/Overland and Rubicon models, it's stronger than the factory Dana 44, addressing common failure points during off-road use with larger tires.
