LAS VEGAS, Nov. 4, 2008 – Designed to offer the best performance, most compact design and lightest weight, the new Dynatrac ProROCK44™ axle delivers solid strength, increased ground clearance and unmatched component quality for stock or lifted 1997 to  present Jeep® Wrangler JK and TJ models.

“We built this axle to satisfy the desire of Jeep owners looking for extreme capability and industry-best Dynatrac craftsmanship. We wanted to deliver the same performance benefits of our iconic ProROCK60 axle in a smaller, more compact design and with the convenience of running the enthusiast’s choice of stock or aftermarket drivetrain setups,? said Dynatrac President Jim McGean. “The new ProROCK44 was designed to provide the level of performance you have come to expect from the Dynatrac brand.?

The new Dynatrac ProROCK44 axle for Jeeps includes a patent-pending,  Dynatrac-exclusive high ground clearance design, constructed from massive 2.75-in. or 3-in. wall tubing; high-pinion Dana 44 replacement housing utilizing stronger, new-generation Dana 44 ring and pinion gear and axle shafts with larger U-joints; and every housing includes new, stronger Dynatrac Pro44 end-forging ideal for running big tires and maintaining camber under severe use. The ProROCK44 axle also features extreme-use, precision-fabricated steel suspension brackets that are 50-percent thicker and stronger than OE.

Providing the ultimate in convenience to the Jeep enthusiast, the new axle from Dynatrac is completely bolt-on and customizable for stock or lifted Jeeps. Jeep owners can re-use stock gearing, axle shafts and brakes during installation and is fully compatible with aftermarket drivetrain components.

Each ProROCK44 axle is backed by a 12-month, unlimited mileage warranty. 


  1. will the prorock44 bolt on to my 2008 jk 2dr with a two inch spacer lift? also what is the biggest tire size i can run with my two inch spacer lift with my 16×8 rims?

  2. yes, it will bolt right up and the biggest tires you can run with 16×8’s is a 33″ tall tire. if the tires are 12.50″ wide, you just need to make sure that you have 4.5″ of back spacing or less on your wheels or else you will have some rubbing issues.
