The Rust Buster RB7808R Front Cab Mount is designed for the right (passenger) side of 2001-2010 Chevy Silverado and GMC Sierra 2500HD and 3500HD trucks, fitting all cab and bed configurations. Built to OE specifications, this mount restores proper cab support in a common rust-prone area of the frame.
Constructed from heavy-duty 7-gauge steel, the RB7808R provides a precise, factory-correct fit when welded in place. For bushing replacement, see RB780011 or RB730045. Each mount 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 front cab mount delivers a durable, professional-grade solution for GM HD truck frame restoration.
