ProRock 60®

ProRock 60®

The Dynatrac ProRock 60® was the first of its kind when it was unveiled in 2002. Today, it’s an off-road performance standard to which all other Dana 60 based axles are compared.

And now, you can have a ProRock 60 front and rear axle for your 2006-2017 Jeep JK at the lowest price ever offered! Click here to view several specially-configured front and rear ProRock 60 packages for the Jeep JK that come complete with ARB Air Lockers and 5.38:1 gears, ready to bolt in. 

 

Custom ProRock 60 axles can be built for the Jeep TJ, XJ, CJ, WJ and just about any other type of 4x4. They are available in standard and custom applications with 35- and optional 40-spline shafts. The nodular-iron ProRock 60 housing combined with the 9¾-inch high-pinion gearset supplies “1-ton” strength and durability as well as improved driveshaft angles and driveshaft ground clearance, especially on short wheelbase 4x4s and front-axle applications. Dynatrac ProRock 60 front axles include massive steering joints, end forgings and wheel ends to provide the ultimate confidence. Dynatrac JK axles include exclusively designed ABS and stability control sensor mounts to maintain all factory function of these systems.


ProRock 60 axles are available with either Warn or optional Dynatrac DynaLoc™ locking hubs. When you use the DynaLoc locking hubs with our exclusive Stub Hub kit, the overall package is 4.75-inches narrower. That means that the hubs tuck into the wheels better with 2.388-inches per side.
