The Rust Buster RB7517R Center Frame Repair Kit is a heavy-duty frame restoration solution designed for the right (passenger) side of 2006-2010 Hummer H3 SUV models. This repair section caps the frame from the bottom below the cab, reinforcing weakened or rust-damaged areas while maintaining factory-correct alignment and strength.
Constructed from heavy-duty 11-gauge steel, the RB7517R measures 23.25 inches in length and features matching OE holes for precise fitment. Integrated cut-outs for center crossmembers ensure proper clearance and compatibility with existing frame components during installation. Each kit ships with an oil protective coating to help prevent oxidation during transit and installation. For long-term corrosion protection, Rust Buster recommends sealing the repair with Rust Buster Rust Converter Paint RB9917 after installation. Welding is required. Backed by Rust Buster’s Lifetime Warranty, this repair kit provides a durable, professional-grade solution for restoring the structural integrity of your Hummer H3 frame.
