Features and benefits:
Made in the USA – Dynatrac's American-made quality and warranty is standard equipment on all ProRock 44™ housings and assemblies.
Dynatrac ProRock high ground clearance design (Pat.Pend.), with big 3-inch”, thick wall tubing. Did you know that stock TJ Dana 44 front axles only have 2.5” x .25” wall tubing?
The ProRock 44™ is a high-pinion Dana 44 replacement housing designed to capitalize on the advantages of the stronger “Next Generation” Dana 44 ring & pinion.
Did you know that all stock TJ Rubicon Dana 44 rear axles were low-pinion? Fact - High pinion gears and housings are stronger than their low-pinion counterparts when installed in a front driving axle application.
The Next Generation Dana 44 gear set has a larger ring gear and a larger pinion shaft than previous Dana 44s.
Each housing also includes Dynatrac’s new Pro44 end forging which is much stronger than stock and very important for running big tires. They will maintain proper wheel camber even under severe use.
This is a actual steel forging made in the USA, not an imported casting like the other guys.
TJ/XJ Owners - The ProRock 44™ housing is fully compatible with your existing stock Dana 30 and Dana 44 outer axle shafts, knuckles, hub bearings, and brakes.
The TJ ProRock 44™ housing requires a new locker (3.73 and down), ring and pinion (JK Rubicon), and custom length inner axle shafts.
Extreme-duty, steel suspension brackets are 50% thicker and much stronger than stock brackets. All are computer designed and CNC manufactured in the USA.
Want to add stronger shafts, change ratios, or upgrade to a locker? No problem! Dynatrac has upgrade packages to fit your budget.
You can buy a finished ProRock 44™ housing to build an axle in your own shop, or order a complete customized assembly from the professionals at Dynatrac.
