The Rust Buster Rear Frame Stiffener set helps strengthen your rear CJ frame rail for both driver and passenger sides. The EZ Slip design allows the repair section to slide onto the frame and will include all the factory needed holes and mounting locations. We use the latest in CAD design to model each repair section before it is laser cut, formed and finish welded. Our repair sections will help to keep your Jeep on the road for years to come.
