Our Boxing plates are cut from 10 gauge steel. Full length boxing plates are cut in half for economical UPS shipping.

Partial front boxing plates are designed to box the frame in the critical areas of front suspension attachment points and motor mount placements. These are 6" ahead of axle centerline and run to 18" behind centerline.

Partial rear boxing plates start where the frame starts to roll up and extends to the shock/coil-over/Shockwave mounting crossmembers typically fall. These are 20" ahead of axle centerline and run to 6" behind centerline.
