What thickness is the wall?
mine is a stock 2 peice and its been spun up to 6200ish..
4700rpms in 4th with the converter locked ~157mph
wont ever do it again, but it was fun at the time.
Are you goin for TQ holding factor or top speed factor?

I had a 3.5'' steel shaft made. Love it, Works great, very strong.
I had asked a few members who have Forced induction what to use, i didnt want to spend 600$ on an alum shaft, IIRC it was Sharpshooter, Brent1976 and ( damn memory) but anyway these guys run a 3.5'' steel shaft with no problems, Russ' truck and mine are heavier than yours so i say 3.5'' as i have no experience with the 4''. Brent1976 has a reg. cab turbo and runs mid 11's .
BTW my shaft ( lol) was 273$ with an HD joint installed and my stock yoke, high speed balanced. Been up to 130++ , no vibrations.
