What's easy to install, made in the USA, and capable of eradicating the issue of bent axle housings in Jeep JKs and TJs, while offering increased strength and ground clearance? The Dynatrac ProRock 44, of course. Created based on the same design principles found in the venerable Dynatrac ProRock 60 axle, the new ProRock 44 boasts the same benefits in a smaller and lighter package.

Dynatrac offers its ProRock 44 axle assembly in various stages of build, ranging from simply the housing itself without tubes, to complete finished assemblies with tubes, JK suspension brackets, and end forgings. Complete JK- or TJ-ready assemblies with all internal and external parts are also available as are customized assemblies designed for special applications.

The Dynatrac ProRock 44 is designed as a direct replacement for the "New Generation" Dana 44F axle found in 2007-and-newer Jeep Wrangler JKs. What parts does "direct replacement" include? All of them. Order a complete ProRock 44 housing with suspension brackets in place and you can transfer your factory or aftermarket JK ring and pinion, electric locker, inner and outer axle shafts, knuckles, wheel bearings, and brakes to create a complete ready-to-bolt-in axle assembly. The ProRock 44 also accepts the knuckles, wheel bearings, and brakes from Dana 30 JK front axles, as well Dana 30 and Dana 44 TJ front axles. Or, Dynatrac can supply all of the parts and ship you a complete, ready-to-bolt-in assembly. No welding, no cutting, no grinding; bolt for bolt the ProRock 44 fits the JK like a glove.

In addition to its standard 3-inch-diameter by 5/16-inch-thick axle tubes (stock is 2.5x0.25-inch) the ProRock 44 offers greater housing rigidity and strength and the highest ground clearance of any Dana 44 axle. It offers a high-pinion design and is equipped with the same degrees of pinion and caster as a stock JK axle. The ProRock 44 is also available in an "Unlimited" version that offers even thicker axle tubes and increased caster to accommodate taller lifts.

If you're sick of nursing your JK frontend through a trail for fear of damage then the Dynatrac ProRock 44 is your answer. The ProRock 44 has been tested against other popular methods of adding strength to the front axle, such as sleeving, gusseting, and re-tubing, and it beats them all. Check out the photos to see why. Your JK or TJ will thank you with unbeatable and unbreakable trail performance.
