The Rust Buster RB7609 Fuel Tank Crossmember is a heavy-duty replacement designed for 1994-2004 Chevy S10 and GMC Sonoma trucks, fitting all cab and bed configurations in both 2WD and 4WD applications. This crossmember mounts to the inside of the frame rails just rear of the front bed mounts, restoring proper fuel tank support and frame integrity.
Constructed from heavy-duty 11-gauge steel, the RB7609 measures 39.60 inches in length and features OEM-style hole locations for a precise, factory-correct fit. The crossmember installs using a bolt-on design and includes Class 10.9 mounting hardware for secure attachment to the frame rails. Each unit 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 fuel tank crossmember provides a durable, OE-style solution for S10 and Sonoma frame repairs.
