The Rust Buster RB7805R Center Frame Repair Kit is designed for 2001-2010 Chevy Silverado and GMC Sierra 2500HD and 3500HD trucks with single rear wheels, fitting Extended Cab and Crew Cab configurations. This repair section reinforces the center portion of the frame, addressing corrosion without requiring frame cutting.
Manufactured from heavy-duty 7-gauge steel, the RB7805R measures 38.7 inches in length and caps the frame from the side for a no-cut installation. Integrated perforations allow installation without removing the center cab mount when applicable, while OE-style holes ensure a precise, factory-correct fit. The kit includes new Class 10.9 hardware and 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 center frame repair kit delivers a durable, professional-grade solution for GM HD truck frame restoration.
