Mopar and Dana co-develop Jeep Wrangler axles


Mopar, the service and parts brand of FCA US LLC (Fiat Chrysler Automobiles), has teamed up with Dana to introduce new Jeep Performance Parts (JPP) axles for the all-new Jeep Wrangler. The collaboration between Mopar and Dana is a continuation of a 70-year-plus relationship, which works to delivers OEM quality parts to current-generation Jeep Wrangler owners..

One of the first axles is the ‘JPP Ultimate Dana 44 AdvanTEK’, designed for off-road-loving Jeep Wrangler owners. High-strength features include AdvanTEK gear technology that reduces gear set packaging with more strength and durability, allowing for a condensed carrier and improving ground clearance. Chromoly 4340 axle shafts, thicker quarter-inch steel bracket mounts, thicker 9.5mm tubes and upgraded 1410 U-Joints also increase trail durability. A nodular iron differential cover adds to the rugged appearance while providing extra ribbing for strength and increasing overall rigidity.

The high-clearance carrier design adds an additional 0.5in of ground clearance, and an expanded range of gear ratios (4.56, 4.88, 5.13 and 5.38) helps accommodate for a variety of tire sizes. The direct bolt-in axle assembly allows use of OEM components and provides virtual ‘plug and play’. The axle assembly includes electronic differential lockers already installed.
