Frame Repair Sections

Has the frame rusted through at the leaf spring mount or under the tank? Here you'll find pre-formed frame sections, crossmembers and brackets that replace the weakened areas. That way you can repair the damaged parts instead of replacing the entire frame when you restore a pickup or keep one on the road.

What do the parts cover?

The category includes parts that replace rusted or damaged areas of the frame. These can be left- or right-hand frame sections, e.g. at the leaf spring mount or over the axle, crossmembers for the transmission, ABS or tank, as well as tank brackets and bed brackets. At RustBuster, the parts are listed for specific models, e.g. Ford F-250/F-350 Super Duty, Dodge Ram 1500, RAM 2500/3500, GM Pickup, Toyota Pickups and Toyota Sequoia. We also carry parts from UMI Performance in this category.

How to choose the right part

• Year and model: The frame's shape and holes can vary between model years, so they must match the part number.
• Cab type: For some models, the part depends on whether the vehicle is an Extended Cab, Crew Cab or Mega Cab.
• Side: Many sections are available separately for the left and right side.
• Extent of damage: Measure where the sound metal begins so the section covers the entire weakened area.

Installation and finishing

A frame repair typically requires cutting, welding and precise measuring so that the axle positions are maintained. So consider whether a workshop should do the job. Rustproof both the new part and the existing frame afterwards, and inspect the joints regularly. Whether the repair passes inspection depends on the workmanship and the vehicle. If the frame also needs stiffening, take a look at reinforcement plates and chassis braces, or find more parts under chassis components.

Frequently asked questions

Do I need a part for the left or right side?

Many frame sections are available in a left and a right version. If both sides are rusted, you will typically need two parts. Check the product description to see how the side is defined before you order.

Can a repaired chassis frame pass inspection?

That depends on how the repair has been carried out and on the specific vehicle. Welds on load-bearing parts must be professionally done. It's a good idea to clarify the requirements with an inspection centre or workshop before you start.

How do I prevent rust from returning after the repair?

Remove all rust at the transition to the old frame, and rustproof both inside and outside after welding. Cavity wax treatment and regular underbody washing, especially after winter driving, can delay new corrosion.
