C021280-1[1] In the planning of my 1989 Chevrolet Camaro, I have had an idea. In addition to the six-speed (or more) transmission, I am considering designing a two-speed rear axle similar to those found in larger, semi-trucks, dump trucks, etc. In doing so, would this create more of a problem than good? If the transmission’s gear ratios are far enough apart or high enough, could I theoretically get higher speeds or would it simply create a confusion of gears in which I will spend all of my time shifting instead of accelerating?

This also could be applicable to any vehicle such as a common pickup truck and would increase fuel economy as well as hauling/pulling power.

Any thoughts?
