I have 4.10s stock in my S10 (2.2L 5 spd. manual) and running 31's, I think 4.56s would be ideal but the lowest gearing in a stock S10 is 4.10 so i couldn't just pull a stock rear end and do a direct swap. Does anyone know of a stock rear end with 4.56 gears? Maybe a Silverado rear end? Or would it be easier to just have 4.56 gears put in my current stock rear end?
I think 4.56's would be too much with 31's if you plan on doing any HWY driving, before I went to 33's I was running 4.30's with 31's and I also a 4 cyl and 5 speed and I had a top end speed of maybe 75 and my gas milage sucked.
