Mopar and Dana co-develop Jeep Wrangler axles

0

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.
