Reviving the strength and glory of your 1976-1986 Jeep CJ is now more effortless with the Rust Buster Frame Repair Rear Cross Member. We've seen the toll time takes on Jeep Wrangler CJs, from bent components due to mishandled snatch straps and chains to the ruthless decay of rust. While many might opt for the original factory cross member, we offer something more resilient.

The Rust Buster rear cross member is sculpted from a formidable 3/16-inch steel plate, making it not just a mere replacement but a significant upgrade. With its precision engineering, it flawlessly matches the factory bolt holes for the rear bumper and gas tank skid while providing apt mounting points for the factory corner body mount bushings.

While this cross member comes to your doorstep in pristine bare steel and primed for action, it requires the finesse of welding for installation. Hence, entrusting this task to a professional welder ensures longevity and optimal performance. And as a testament to its unparalleled quality, it stands proudly under the banner of our Limited Lifetime Warranty. Give your Jeep CJ the robust defense and renewal it rightfully deserves with Rust Buster.
