2003 Tahoe/4.56 gears on 33s?

[Em Vee]

I had the H3 which was factory equipped with 33’s and 4.56 using the same transmission. It was great. And still capable to cruise at freeway speeds all day long.

The H3 Alpha edition came with 4.10 gears from the factory not 4.56 so maybe the person you bought it from installed 4.56 gears. But how was it? did it rev too high at highway speeds?

300 rpm is what the difference will be with the tire height increase. If you are that worried about rpm, run 65 instead of 70.
