Rust Buster Rear Frame Repair Kit Left for 2009-2024 Ram 1500 - RB7730L

The Rust Buster RB7730L Rear Frame Repair Kit is designed for the left (driver) side of 2009-2018 Ram 1500 and 2019-2024 Ram 1500 Classic trucks equipped with a 6.5 ft bed. This repair section installs at the very rear of the frame rail, restoring structural strength in a high-impact, rust-prone area.

Manufactured from heavy-duty 11-gauge steel using laser-cut, bent, and welded construction, the RB7730L features OE-style holes for a precise, factory-correct fit. Integrated perforations for the rear crossmember allow you to cut around it if removal is not required, simplifying installation. Each kit 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 rear frame repair kit delivers a durable, professional-grade solution for Ram 1500 frame restoration.
