The Jeep Cherokee XJ (1984-2001) is a rugged favorite, but its factory unibody can weaken under modern mods like lifts and big tires, leading to cracks and flex in the rear areas. Our Inner Rear Unibody Stiffeners are designed to reinforce the inner side of the rear rails, welding in place for boosted structural support and extended vehicle life.

Choose between 10-gauge cold rolled steel (for superior strength through work hardening and a refined finish) or 3/16-inch pickled and oiled steel (thicker, with a scale-free surface for easy welding and rust resistance). CNC-cut for precision, these stiffeners offer square or round weld holes to suit your install. Sold in pairs for full driver and passenger coverage, they're the final pair (4 of 4) in our basic kit—versatile for targeted fixes or rust battles in salty climates. Welding is essential, and some models may require light grinding for fitment.

Proudly fabricated by T-M Fab, your go-to for Jeep solutions built to last.

• Inner Rear Reinforcement: Welds along the inner side of the rear unibody rails, providing added strength to combat lifts, oversized tires, and off-road stress that surpass factory capabilities.
• Material Options for Durability: Available in 10-gauge cold rolled steel or 3/16-inch pickled and oiled steel—choose based on your needs for strength, thickness, and surface quality.
• Cold Rolled Steel Benefits: Processed at room temperature for work hardening, resulting in higher strength, hardness, and a smoother finish ideal for precision applications and enhanced load-bearing.
• Pickled and Oiled Steel Benefits: Hot-rolled base with acid pickling to remove mill scale (unlike standard A36 steel), plus oil coating for rust prevention—offers a cleaner surface for better welding and painting, with good ductility for forming.
• Weld Hole Customization: Select square or round weld holes to match your welder's preference for easier, more efficient installation.
• Precision Design: CNC-cut to fit seamlessly, with welding required (some models may need minor grinding for optimal installation).
• Sold in Pairs: Includes stiffeners for both passenger and driver sides—pair 4 of 4 in our basic kit, ideal as a standalone upgrade or completing a full reinforcement set.
• Rust Repair Support: Excellent for salted-road areas, assisting with rust patching and prevention to prolong your Cherokee's lifespan.
