The Jeep Cherokee XJ (1984-2001) handles tough trails, but its factory unibody can suffer from flex and cracks under heavy mods like lifts and big tires, especially in the center inner areas. Our Inner Center Unibody Stiffeners provide targeted reinforcement, welding inside the rails: on the passenger side from the rear shock crossmember to roughly the middle centers; on the driver side from the same crossmember (including holes for fuel filter and fuel line mounts, plus a notch for the brake line tab) to the middle centers. They also extend to cover the bottom from the centers to just before the bump stops (aligning with inner rears), retaining holes for the rear sway bar.

Designed to overlap T-M Fab or other center stiffeners for double-plated bottom strength, these are offered in 10-gauge cold rolled steel (for superior work-hardened strength and smooth finish) or 3/16-inch pickled and oiled steel (thicker with a clean, scale-free surface for optimal welding and rust resistance). Customize with square or round weld holes. Sold in pairs for complete coverage, they're a perfect advanced add-on to basic kits or for rust repairs in salty environments. Welding is required, with possible minor grinding for fitment.

Proudly made by T-M Fab, your trusted source for Jeep fabrication that delivers trail-tested reliability.

• Inner Rail Reinforcement: Welds inside the unibody rails—passenger side from rear shock crossmember to roughly the middle centers; driver side from the same crossmember (with holes for fuel filter and fuel line mounts, plus notch for brake line tab) to the middle centers—for added strength against lifts, oversized tires, and off-road stress.
• Bottom Coverage Extension: Also reinforces the bottom from roughly the centers to just before the bump stops (where inner rear ends), retaining holes for the rear sway bar.
• Double Plating Design: Engineered to overlay T-M Fab or other brand center stiffeners, creating double-plated bottom protection for maximum durability.
• 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.
• Sold in Pairs: Covers both passenger and driver sides—standalone upgrade compatible with basic kits for advanced reinforcement.
• Rust Repair Support: Ideal for salted-road regions, aiding in rust patching and prevention while extending your Cherokee's overall lifespan.
• T-M Fab Expertise: Engineered for Jeep Cherokee XJ (1984-2001)—minor grinding may be needed; visit t-mfab.com for more XJ upgrades and kits.
