Re: What's everyone running for gears?

3:73 32" tire on my C20 6.0 4l80. Need 4:10 or 4:56 for the work it does. To low of rpm alway dropping into 3rd and 2nd climbing hills.
My suburban is 27" tire 3:42 pulls way better but still would like 3:73 or 4:10 in it. Need to target 2200 rpm at 62 mph for my liking.
