Weight Distributing Hitches

Supercharging is a great way to boost horsepower, and reduce engine life. Some components of a half tonner are pretty hard to upgrade, like frames, rear axles, front suspension components, etc. I do not work for a manufacturer, but I suspect the transmission in a one ton pickup is not exactly the same as one supplied with their half ton models either. Cooling systems are probably different also. If all it took was a spring pack and a set of tires, the builders could save a lot of money building the various models.
