RockJock TJ/LJ/XJ/MJ Johnny Joint Kit Front End Housing 30 or 44 w/ Greasable 1/2in Thru Bolts

If you're looking to get the most flex out of your Jeep Cherokee, Comanche, Grand Cherokee, or Wrangler's front suspension, this Johnny Joint kit from RockJock is a solid option. It replaces the stock upper control arm bushings on the differential housing with high-articulation Johnny Joints. This allows your suspension to move much more freely, which is crucial for off-road performance and keeping your tires on the ground over uneven terrain.

This kit is designed to work with factory Dana 30 or Dana 44 front differential housings. It includes a greasable 1/2-inch bolt for the Johnny Joint, which is larger than stock and requires you to drill out your control arm holes to fit. The kit also comes with a flame-cut steel upright that you'll weld onto the existing bracket base on your axle tube. This method avoids welding directly on the axle tube itself, preventing potential warping. Keep in mind that installation does require cutting and welding equipment.

The steel components are powder-coated for durability, helping to resist corrosion. This kit is a significant upgrade for anyone serious about improving their Jeep's off-road capability.
