Re gearing for bigger tires! Need Advice!

[WhoNeeds4WD]

I have a 1996 C1500 4.3L V6
33" All-Terrains

Thinking about re gearing the axle gears. If i do this, should i go with 4.33 or 4.56

Without knowing whether you have an automatic or manual (I'm going to assume automatic) or what gears you have now (I assume 3.42), the 4.56s will increase your RPMs to about 1950 at 60 miles per hour. If that's cool with you, then go for the 4.56s.

4.33?

Yeah, I assumed he knew something I didn't.
