The installation process for the MOTOBILT MB1500 Wheelbase Stretch Kit for Jeep YJ is as follows:
1. Begin by removing the gas tank, rear axles, and springs from your Jeep YJ.
2. Decide whether you want to keep the factory cross member or remove it completely. If you choose to remove it, cut away the cross member and clean up the frame using an angle grinder with a flap wheel. Grind down the tube for the stock shackle hanger until it is flush with the frame.
3. Whether you remove the cross member or keep it, cut off the end where the body mount attaches. It is recommended to tie the rear of the roll cage into the frame at this point to strengthen it.
4. Ensure that the new cross member sits flush with the frame rails for a good weld onto the frame. The frame rails should end up even or flush with the end of the cross member.
5. Tack weld the new cross member into place against the frame rails to ensure it is square and centered. Add the frame side plates to cap off the end of the cross members and tack them into place as well.
6. Double-check the alignment of all the pieces before fully welding the cross member and side plates to the frame.
7. Once all the pieces are fully welded and cooled down, you can install the bushings, shackles, leaf springs, and the rest of the components.
