If you’re getting into a full on build, you might want to consider boxing the frame in and stopping the cracks before they ever take place. Luckily, West Bend Dyno now offers a COMPLETE 1973 – 1987 C-10 Shortbox Frame Support Kit. When using original or reproduction frame rails, these 10 gauge steel plates are pre-cut and ready to be welded in! Our support plates are designed to box the frame in critical high load areas all the way from the front to the rear. Some grinding may be required to fit each plate inside the frame rail. Take a look at the instructions below for more information!
