Recommended Gears

[silentblinder9502]

I have an LS 2wd with the 17" wheels and the 3.23 gears. I am upgrading to 20" wheels and it has been a long time since I dealt with automotive mathmatics:confused2:. So tell me, what gear size should I upgrade too to not lose any bottom end power? Thanks in advance

I would strongly recommend that you consider 4.10. I have an 07 LTZ with the 3.73 gears and 5.3 engine. Just returned from a 2500 mile trip towing a small tent trailer (1600 lbs). I would have paid lots of money for the 4;10s!
