The 1999–2016 Ford Super Duty lineup marked a new era of heavy-duty dominance — purpose-built with a dedicated chassis, squared-off body lines, and the muscle to handle serious work. Whether powered by the iconic 7.3L Power Stroke or later high-output diesels, these trucks became the backbone of America’s workforce, towing, hauling, and plowing their way into legend. Tough, utilitarian, and unmistakably Ford, they set the standard for what a real truck should be. Rust Buster frame repair kits are engineered to bring these hardworking rigs back to life — restoring the strength, reliability, and pride built into every Super Duty.

Rust Buster frame repair kits are engineered as a safe, proven alternative to full frame replacement—restoring structural integrity without compromising vehicle geometry or OE mounting points. Each section is precision-designed to reinforce known failure areas while integrating seamlessly with the original frame, ensuring proper alignment, predictable installation, and long-term durability. This approach allows you to repair only what’s compromised, reduce downtime and cost, and keep your truck on the road with confidence. Backed by decades of engineering experience, every Rust Buster frame component is built to meet real-world demands and is supported by our Lifetime Warranty.
