Frame Repair Solution. The Rust Buster Rear Frame Repair Kit is designed to replace a worn or rust-damaged rear frame section and help bring back the strength, appearance, and usability of your truck’s structure. It is an important repair component for addressing corrosion in a critical area while maintaining proper support where it is needed most. Built for dependable service, this kit helps restore confidence in the condition of the rear frame.
Construction and Appearance. This rear frame repair kit is manufactured using heavy-duty 7-gauge steel for strong, lasting structural support. It is made to meet or exceed OEM specifications, giving it the quality needed for a reliable repair. To help prevent oxidation during storage and handling, the surface comes coated in oil. Its raw metal appearance reflects its purpose-built design and allows it to be properly prepared during the repair process.
Installation. Installation requires welding, so this repair is best handled by an experienced technician with the proper tools and equipment. Professional installation is recommended to help ensure accurate placement and dependable structural results. Because this is a welded-on repair section, the process is more advanced than a simple bolt-on upgrade and should be completed with care.
Warranty. This product is backed by a lifetime warranty, offering added peace of mind with your purchase. That coverage reflects confidence in the material quality and workmanship of the repair section. For long-term ownership, a lifetime warranty adds valuable assurance that supports the overall value of the kit.
Application. This Rust Buster Rear Frame Repair Kit fits 2011-2019 GMC Sierra 2500 HD models with 6.50-Foot Standard Box.
