ProtoFab manufactures built-to-order bumpers, cages, and trail armor for classic Ford Broncos and now expanding into the Chevy K5 Blazer — all made in-house here in Arizona.

If you’re upgrading a 1966–1996 Bronco, you’re in the right place: our parts are designed for real off-road use, with proven fitment and desert-tested durability. Explore our core product lines like Bronco winch bumpers, rear bumpers, rock rails, interior tube supports / roll cages, and stainless fuel tanks. Everything is built for strength and function, whether you’re protecting sheet metal, improving recovery capability, or adding safety and rigidity. We also provide in-house custom exhaust fabrication for any vehicle for builders who want a clean, properly routed exhaust system that matches their suspension, drivetrain, and intended use.
