Dynatrac Trail-Series 44 Front Axle for Jeep YJ, TJ, JK

If there is one product that Dynatrac is best known for, it is the ProRock 60. In 2002 the ProRock 60 set the world standard for strength, ground clearance and quality. In that same tradition Dynatrac is now very proud to introduce the all new ProRock 44!

If you always wished for a set of ProRocks under your 4x4 but thought that the ProRock 60 was too much for your needs, your wish has finally been granted. The new ProRock 44 has all of the same benefits as the 60, but in a smaller and lighter package that is designed to fit your Jeep TJ or JK like a glove.

Features:

• 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 JK and TJ D44 front axles only have 2.5" x .25" wall tubing?
• The ProRock 44 is a high-pinion D44 replacement housing designed to capitalize on the advantages of the stronger "New Generation" D 44 ring & pinion gears and axle shafts equipped with larger U-joints. Did you know that all stock TJ Rubicon D44 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.
• 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.
• JK Owners - The ProRock 44 housing is fully compatible and ready to accept your existing stock and aftermarket JK D44 ring and pinion gears, lockers, knuckles, brakes and axle shafts. JK owners with D30 front axles can re-use their knuckles, wheel bearings, and brakes.
• TJ Owners - The ProRock 44 housing is fully compatible with your existing stock and aftermarket TJ D44 lockers, knuckles, brakes and axle shafts. TJ owners with D30 front axles can re-use their knuckles, wheel bearings, and brakes.
• 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.

Benefits:

• Saves you money! The new ProRock 44 has big improvements in strength and ground clearance, but lets you re-use your stock or aftermarket JK D44F internal parts, and your JK or TJ wheel ends and brakes.
• Go anywhere! Highest ground clearance of any D44 axle, with the added rigidity needed for bigger tires and off-road use.
• JK and TJ owners can finally say good-bye to bent front housings for good! No welding, No hammering, No grinding! This is not a welded-up and braced housing. It is a new housing designed from the ground-up to handle tough trails, big tires and loaded Jeeps.
• Can be upgraded now or later with new aftermarket gears, axle shafts, and brakes.
• Easy to install – Fits perfectly and bolts into your stock or lifted JK or TJ. No grinding or welding required.
• Legendary ProRock durability for your Jeep vehicle gives you Confidence to Explore®
• Made-in-USA – Quality and first class workmanship throughout. This is not another one of those imported, buyer-beware housings. It’s all made right here in the USA by your fellow American citizens. If you are looking at a competitors product that doesn’t say Made-in-USA, it’s because it probably isn’t.
