This RockJock 4x4 Cylinder Assist Kit is a solid way to take the load off your steering on 2018–2023 Jeep JL and JT builds. It’s built to RockJock’s specifications for their Dana 60–based axle setups, so everything works together like it should—no guesswork or mismatched components.

The system is centered around a single-ended assist cylinder with the stroke limited to 7.375", giving you the right balance of steering control without overextending your setup.

The weld-on design keeps everything tight and where it needs to be, especially once you’re into bigger tires and tougher terrain. This kit also includes a matched hose kit, so you’re not piecing things together or chasing fittings.
