Dynatrac Axles for the Long Haul

Most factory axles have one deficiency or another and for the most part, bolt-on parts can’t eradicate these issues. Some of the issues are axle tube and/or knuckle related, some are housing related, some are internal issues, and some fall in the all-of-the-above category. Luckily, however, all of these axle related maladies are easily remedied by Dynatrac via installation of one of its performance-built Pro Rock 44 and Pro Rock 60 bolt-in axle assemblies.

We have used Dynatrac’s Pro Rock 60 assembly in both TJ and JK applications and have also installed Pro Rock 44s in various JK applications, all to exceptional results. This time our goal was to build a competent front assembly to reside at the front of our family fun adventure rig, a 1997 Jeep Cherokee Sport four-door 2WD that we’re converting to 4WD. You can expect to see more articles about this particular 4x4 convert in upcoming issues.

For JK owners the best part about the Pro Rock 44 assembly is that it permits re-use of stock or aftermarket JK Dana 44F parts, including locker, gears, inner and outer axle shafts, knuckles, hub bearings, and brakes. It is also compatible with XJ and TJ Dana 30 and Dana 44 outer axle shafts, knuckles, hub bearings, and brakes. The TJ/XJ Pro Rock 44 assembly requires a new locker (Dana 44F, 3.73 and down), ring and pinion (JK Rubicon style), and new inner axle shafts.

Dynatrac manufactures its own specially designed housings, knuckles, spindles, housing ends, wheel hubs, brake mounting brackets, spring and suspension mounts, axle retainers, axle shafts, and tube assemblies. All castings are 100-percent made in the USA and offer well-engineered factory fit and function across a wide range of 4x4 applications.

Dynatrac axles are available in all popular wheel bolt patterns, including, but not limited to: 5 x 4.5 (YJ, TJ, and XJ); 5 x 4.75 (GM); 5 x 5.0 (JK, GM); 5 x 5.5 (Ford, Jeep), 5 x 6.5 (Landrover), 6 x 5.5 (GM, Toyota); 8 x 6.5 (Ford, GM, Chrysler); and 8 x 170 mm (Ford Super Duty).

All of the hardware used throughout every Dynatrac axle assembly is U.S.-sourced Grade 8 quality. Dynatrac uses genuine Dana/Spicer or Precision Gear ring and pinion sets and also offers a wide range of differential and upgrade options with every axle it builds.

You’ll see more of our Dynatrac ProRock 44 front axle assembly in an upcoming issue as we carry out its installation in our 1997 Jeep Cherokee. For now, check out the photos and captions to get a behind the scenes look at the construction of a ProRock axle assembly.
