The Rust Buster RB7100 Over Axle Frame Stiffeners are designed to reinforce the frame rails on 1995–2004 Toyota Tacoma trucks. Built from heavy-duty 7-gauge steel, these 42.00-inch stiffeners cap the frame between the fuel tank and spare tire crossmembers. They retain all factory hole locations for installation accuracy and are sold as a pair to strengthen both driver and passenger sides. Ships with an oil-based protective coating to prevent oxidation prior to installation. Welding required.

These stiffeners reinforce a structural section of the Tacoma frame that commonly weakens over time due to moisture, salt, and off-road conditions. Rust Buster engineered the RB7100 using high-precision scanning and CAD technology to match OEM contours and ensure a perfect fit on both sides of the truck. Built from durable 7-gauge steel, they provide long-term strengthening and extend the useful life of the frame. Covered by Rust Buster’s Lifetime Warranty.
