Was a 4.11 rear end available in '95 from the factory? I was on the freeway
last night and noticed that with 31" tires at 60mph, the truck is pulling about
2000rpm. I've read in the archives that trucks with the 3.90 rear end with the
stock tires (which are a good 3" shorter in diameter than my 31" tires) pull
about 2000rpm at 60mph. This seems odd to me as the underhood sticker doesn't
indicate anything about the different gear ratio - but if I had the standard
3.22 gears I don't think I'd be pulling the RPM I'm pulling at 60mph with the
size of tires I have.
I guess I'll be doing the string trick next time I'm under the truck...
