My concern would be the even lower gearing in a 3600 rear. My question is why are you interested in chqnging it if it isn't to gain a higher ratio?

I might like a higher ratio too but the truck doesn't get driven enough to ever be cost effective. Besides mine will run 65+ MPH now although it is screaming so 50 is fine and that matches my brakes as well.
