1955-57 Chevrolet Car Frames & Chassis

Progressive Automotive, 1955, 1956, 1957, chevy, Chevrolet, chassis, frame, belair, hardtop, convertible, nomad, delivery, handyman, wagon

  These frames & rolling chassis are designed to fit 1955, 1956 and 1957 Chevrolet cars. Call for information and pricing for your specific frame or chassis needs. Proudly manufactured at our shop in Baltimore Ohio.

  Our hot rod frames feature our new boxed frame rails, constructed from 10 gauge (true 1/8”) sheet steel. Our rails mimic the original shape, contours and widths of the original frame, unlike mandrel bent box tube. The rails are fully welded and the corner welds smoothed.

  Unlike the original Chevrolet frame, our street rod frames incorporate our tubular crossmember. Not only does this create a stronger frame, but it allows room for all of the popular transmissions.

 Other options are available, such as Custom ride heights, Air ride, brake upgrades, new 3rd members and Kugel Suspension.
