Progressive Automotive offers Hot Rod, Street rod and truck frame boxing plates that are CNC cut from 10-gauge (.135) steel. These boxing plates provide added strength and reinforcement to the frame rails.
The full boxing plates are cut into four pieces per frame rail for the lowest shipping cost possible.
For those looking for partial boxing plates, Progressive Automotive offers front and rear options. The front partial boxing plates are designed to box the chassis in critical areas such as front suspension attachment points and motor mount placements. They typically start approximately 6″ ahead of the Front Axle Center Line and extend 20″ behind it.
Similarly, the rear partial boxing plates start where the rear suspensions attach and extend to where the shock/coil-over/air ride mounting cross members are located. They generally start approximately 20″ ahead of the Rear Axle Center Line and extend 6″ behind it.
Boxing plates are non-refundable, but Progressive Automotive offers the option to exchange them for custom cut boxing plates based on a provided template.
Progressive Automotive takes pride in manufacturing their products at their shop in Baltimore, Ohio, U.S.A. emphasizing their commitment to quality and craftsmanship.
