Works with any engine. The front pivot brackets are fully welded and painted. They bolt to the stock shackle mount and lower from bumper mounting holes and additional holes that you must drill in the frame. This S.R.S. mounts the shackle 'through' the frame. You must drill a hole in the frame and weld a tube in it, then polyurethane bushings (provided) insert into the tube and the shackles (provided) hang from each side of the frame. This method will not lift the Jeep.
