Rust Buster Rear Frame Crossmember for 2014-2019 GM Pickups - RB7398

The Rust Buster RB7398 Rear Frame Crossmember is a heavy-duty frame repair and replacement solution for 2014-2018 Chevrolet Silverado 1500, 2014-2018 GMC Sierra 1500, 2019 Chevy Silverado LD, and 2019 GMC Sierra Limited trucks. Designed to fit all cab and bed configurations, this crossmember installs in place of the factory OEM rear crossmember at the end of the frame rails.

Manufactured from heavy-duty 11-gauge steel, the RB7398 measures 40.7 inches in length and provides critical structural support for the spare tire plate and rear section of the frame. Please note, the spare tire plate is not included; if required, Rust Buster recommends RB7342. Each crossmember ships with an oil protective coating to help prevent oxidation during transit and installation. For maximum corrosion resistance and long-term durability, Rust Buster recommends finishing the repair with Rust Buster Rust Converter Paint RB9917. Welding is required. Backed by Rust Buster’s Lifetime Warranty, this rear frame crossmember delivers a strong, factory-correct solution for restoring the integrity of your GM truck’s frame.
