I was running 3.42's on my 315's with a bb tune. I still had power but would have preferred to have 4.56's.
My first truck! 04 Chevro...no wait...yes...no...wait..

Use the second calculator on this site, it seems to be pretty close. 4L60E has a .696 overdrive so use that for trans ratio

Oh and truck looks good with the preds, those wheels just look perfect on the nbs trucks

Not right.
I have 4.88's and 35's.
I'm at about 2500 at 70mph
If you are going to be running 35's. go 4.88.
You will only turn about 150rpm more at hwy speeds than you would with 4.56
4.88 will give you much more gear, and much more options in the long run.
Go 4.88 and you'll be happy. You only want to hear once. It's expensive. Lol
