Rust Buster Forward Fuel Tank Crossmember for 2001-2010 GM HD Pickups - RB7812

The Rust Buster RB7812 Forward Fuel Tank Crossmember is a heavy-duty replacement designed for 2001-2010 Chevy Silverado and GMC Sierra 2500HD and 3500HD trucks, fitting all cab and bed configurations. This crossmember installs in place of the OEM forward fuel tank crossmember, restoring proper fuel tank support and frame integrity in a common corrosion-prone area.

Constructed from heavy-duty 11-gauge steel, the RB7812 measures 42.7 inches in length and includes an integrated evaporative canister bracket for factory-correct routing. The kit features a bolt-on installation and includes Class 10.9 mounting hardware, requiring no welding. Each crossmember 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. Backed by Rust Buster’s Lifetime Warranty, this forward fuel tank crossmember provides a durable, OE-style solution for GM HD truck frame repairs.
