Level 3 chassis stiffening kit for the 66-70 Dodge 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
  • Front Inner Fender Braces
  • Front Lower Core Support Brace
  • Rear Spring Relocation Kit
  • Mini Tub Kit

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.

USCT inner fender braces adds incredible triangulated strength to the front end of your Mopar sub-frame front end. The kit includes CNC cut plate steel to box in the top of the OEM shocktower and tie it to the OEM fender panel. Designed to resist frame rail twisting and spread suspension loads across the OEM unibody. An absolute must when adding coil over suspension that moves the suspension loads away from the torsion bar crossmember and places them all onto the front sub-frame.

USCT front lower core support brace installs between the front frame rails, under the factory radiator. Can replace the factory thin sheetmetal support or can be installed on top of the factory core support. Adds rigidity to the extreme front of the factory frame rails. 1966-1970 Dodge Plymouth B Bodies.

USCT leaf spring relocating kit is self aligning off the factory leaf spring mounting holes and includes instruction on how to cut the factory frame rails, locate and weld in the new front and rear mounts and measure to be sure you are straight and square. This kit won't make you a chassis shop, but it will help an advanced hot rodder gain up to 8"of tire tread space in the back of that Mopar!

USCT mini tub kit allows you to Mini-Tub your B-body Mopar in a weekend with our pre-fabricated wheel tub filler.

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.
