steel or aluminum driveshaft?

Mark...go to the Mark Williams website and look up "critical speed"..... while a performance improvement is nice you need to spec out your driveshaft based on your trap rpm you achieve.....the diameter and material type will be decided once you have your shaft length and trap rpm....

as an example for my stocker build I needed a shaft 54" long and needed to handle at least 7000 rpm and since it had to be steel I required a 3.5" chromoly shaft.....while aluminum can give you a higher critical speed it is less durable.....
