Level 1 chassis stiffening kit for the 66-70 Dodge & Plymouth B-Body models. Purchasing these components as a kit offers a substantial savings over purchasing the components individually.

Kit includes:
  • Weld-in Frame Connectors
  • Front & Rear Torque Boxes

USCT weld-in frame connectors are CNC Machine cut from 12ga steel (original factory rails are made from 16 gauge material) and CNC bent for a precision fit, these frame rail connectors are designed to be welded in to your existing unibody floor pan. No cutting of the floorpan is required and once welded in, they create a fully boxed frame rail connector that is stronger than the original factory frame rails!!

USCT torque boxes are designed to add strength to your Mopar unibody in several critical areas. The factory added OEM torque boxes on the high-HP, high torque cars and convertibles. Hemi cars, six-pak cars etc. had torque boxes added by the factory engineers. Our interpretation of the OEM pieces improves on that proven design. We made them stronger by using 1/8" thick steel and having them CNC Machine cut and CNC bent.

About Auto Metal Direct

Auto Metal Direct is a team of true car guys with years of experience in sheet metal reproduction, car restoration and paint/body work. We believe that quality is not subjective!  Our mission is to provide the best customer experience for the Ford, Mopar and GM classic car markets - both in products and in service. 

Our panels are made from proper gauge steel and include all correct-as-original clips, tabs, flanges, bends and seams. Each time a prototype body panel comes off of a new tooling, we test fit it on a car. The marked up prototype is then used to change and improve the tools, and a new prototype is produced. This procedure might be repeated multiple times but, once the part is finally approved, you can be assured of a quality part.
