2wd or 4x4? That's going to decide it. Because if its 4x4, you can't run 4.30s or 4.88s. At least I know you can't run 4.30s.... they aren't offered for the front dif.

Ah. Yea 4.30
Even with 33s?! Hell, I had 4.10s with a 30" tire in my last 4.8!
456s worked real good when i had the 4.8 on 22s 31" tall
My 4.10's on a 30 inch tire actually improved city mileage and didnt affect highway any measurable amount.

Most sports require one ball, motocross requires two.
Racing isn't a matter of life and death, it's much more important than that.
My brother does about 90% city driving. I did get a chance to log fuel mileage on the highway one time, and it was around 15. Take into consideration the truck has 200k miles, weighed down with tools, ladder racks with 2-3 ladders...
The nice thing about a properly geared 4.8 is how it is closer to being in the powerband during highway driving. Less downshifting and easier to maintain speed.
Big slow mud truck with a TUNE!!!!!!
