The front pivot brackets are fully welded and powder coated. They bolt to the stock shackle mount and lower front 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. We don't just use standard bolts in critical pivoting areas like our competitors, our bolts are greaseable that makes your system superior to others out on the market. The front driveshaft will need to be modified with a long travel slip in stub.
