About 15 years ago, Jim Carter Truck Parts decided to reproduce the “real” GM step plates used in the years of 1947-55. Though there were hundreds of step plate designs available during the early years, only one is pure Chevrolet/GMC and was made available by the GM dealers.
No lettering exists so they will fit both Chevrolet and GMC. They are stamped steel with black exterior paint. In the center between the outer raised edges are a non-slip adhesive sheet. This attractive accessory prevents visual scratches when people step on restored boards.
MOST IMPORTANT: GM referred to these accessories as “Safety Treads”. It was discovered from dealer feedback that on occasions a wet metal running board used to enter or exit a truck with smooth shoe soles caused a major fall from slipping. Broken bones sometimes were the results. Thus, the creation of “Safety Treads”.
Just like GM made them!
