Engineered to be a direct-fit, bolt-in solution for the Jeep Wrangler JK, Ultimate Dana 60™ axles are built for superior strength inside and out.

The full-float design of the Ultimate Dana 60™ axle means that the vehicle weight is carried by the housing instead of the shaft. So, you can enjoy a greater load-carrying ability wherever your Jeep takes you. The Ultimate Dana 60™ axle features Spicer® 35 spline SAE-4340 nickel chromoly steel axle shafts to help meet the rigors of off-road, providing maximum strength and durability for vehicles with larger tires.
