Gasser Straight Axle


The plans are for the most part universal in nature and as such will work fine on most any car or truck. There are many things to consider to install a straight axle and have the car handle correctly. I have driven my straight axle coupe in excess of 130 mph. The car drives straight and predictably at speed because the installation considers important steering geometry principles.  Do it once, do it right with these plans.

The design of the axle it self was done specifically for a 37-39 Chevrolet but the only possible change required for other applications would be to alter the track width which of course only requires a change in one dimension. The plans will accommodate several types of spindles.
