The Jeep JL is larger in all measurement than a JK. The Dynatrac ProRock XD60 front and ProRock 80 rear axles for a JL measure 72 1/2 inches from wheel flange to wheel flange. The 1550LT wheel ends let the front axle steer extremely tight even though the vehicle is wider and has a longer wheelbase. The front axle is outfitted with an Eaton ELocker and 5.38 gears. The XD60 axle uses a 10.1-inch ring gear, and the massive 3 3/4-inch-diameter axletubes help the axle assembly be the strongest and lightest in its class.
