The Dynatrac ProRock 44™ front axle offers incredible strength and unmatched ground clearance. We engineered this ProRock 44 as a direct replacement housing for 2007-2018 Jeep Wrangler JK front axles, replacing the factory Dana 44, addressing the critical areas that fail when larger tires are installed and the vehicle is used regularly off-road.
The Dynatrac ProRock 44 offers more strength and features than competitors:
When using the axle configurator on this page, you can choose a ProRock 44 housing. If you the ProRock 44 is for use in factory Rubicon, you will re-use the factory electric locker. For all others, choose a completely assembled ProRock 44 which will come with your choice of new differential or locker. If you choose an assembled ProRock 44 with a new differential or locker, the price includes the ring-and-pinion gearset, gear setup and install kit, yoke and the axle will come to you assembled. You will need to add the knuckles and brakes from your factory axle.
