About this part

Product Details

If you're looking to get the most out of your Jeep Wrangler's suspension, this RockJock Johnny Joint kit for the front axle housing is a solid option. It's designed to replace the upper control arm bushings on factory Dana 30 or 44 differentials, allowing for significantly more articulation. This means your wheels can move more freely over uneven terrain, keeping your tires in contact with the ground for better traction.

This kit includes a Johnny Joint insert for the differential gear case and a flame-cut steel upright that's already fitted with a Johnny Joint. The installation involves cutting off the top of your stock bracket on the axle tube and welding the new RockJock piece onto the existing bracket base. This method is smart because it avoids welding directly onto the axle tube, which can prevent warping and keep your alignment true. You'll need cutting and welding equipment to get this installed, and greasable hardware is included to keep things running smoothly.
