Rust Buster Mid Frame Repair Kit for 2001-2010 GM HD Pickups - RB7804R

The Rust Buster RB7804R Mid Frame Repair Kit is designed for 2001-2010 Chevy Silverado and GMC Sierra 2500HD and 3500HD trucks with single rear wheels, fitting Crew Cab and Extended Cab configurations. (For Single Cab applications, see RB7818.) This repair section installs between the center and rear cab mounts, restoring structural integrity in a common rust-prone area.

Constructed from heavy-duty 7-gauge steel, the RB7804R measures 32.9 inches in length and caps the frame from the side with no cutting required, simplifying installation. Precision OE-style holes ensure a factory-correct fit prior to welding. Each repair section ships with an oil protective coating to help prevent oxidation during transit. For long-term corrosion protection, Rust Buster recommends finishing the repair with Rust Buster Rust Converter Paint RB9917. Welding is required. Backed by Rust Buster’s Lifetime Warranty, this mid frame repair kit provides a durable, professional-grade solution for GM HD truck frame restoration.
