From quadratec.com: RPMs based on Tire Size, Gear Ratio, @ 65 MPH

Yellow = Highway ; Good Fuel Economy
Green = Daily Driving ; Best/Optimum Fuel Economy
Blue = Most Power/Towing ; Reduced Fuel Economy

Thanks for the info. Still a tough decision as some say 4.56 is too steep and others say its just right. Still a little ways a way, but wanted to see what everyone was thinking about their gear choices.

You should also note that is based on a 1:1 ratio (3rd Gear) OD/4th will be less.

4.56 is AWESOME if you drive in the city stop/go traffic. The extra power is a bonus.

For higher speeds 65+ mph....sucks.
