ZJ (1993-1998) Jeep Grand Cherokee Unibody Frame Stiffeners – Front, Middle, and Rear Sections

ZJ (1993-1998) Jeep Grand Cherokee Unibody Frame Stiffeners - Front, Middle, and Rear Sections.

The weld-in frame stiffeners to reinforce or repair the front, middle and rear sections of your Grand Cherokee. These frame stiffeners are constructed from 10ga steel. Precut for welding and formed to fit the front, middle and rear frame rails of your ZJ. One-piece design for each section, makes for faster installation with less guesswork. Hugs tight to the bottom frame rails, increasing thickness, rigidity, and strength of the frame. Prep work and welding required.

Instructions:

1. Very important to clean frame rails before installation.
2. Use a jack to hold in place when marking where to clear and a grinder to remove the coating.
   1. The better you do here, the faster the rest of the job will go. It's dirty work, but an extra 10-20 min could save you an hour or two and prevent blowing holes in your frame.
3. Use jacks and clamps to hold in place while you confirm hole alignments and tack weld. Stitch weld edges 50-60% and plug appropriate weld slots.
4. Wear all PPE when grinding and overhead welding. Ear plugs and safety glasses even under your hood when overhead welding. (Sparks in ear hole very bad). Or support your local welder and let a professional do it.
