Changing the gears in my suburban
I have decided to change the gears in my suburban (2008 5.3L 4sp auto), but not sure how much of a change to make. I currently have 3.73 gears, and was thinking 4.30 because 4.10 doesn't change much,...

4.30 will put you right at 3000 rpm.
4.56 you are looking at 3180 rpm.
Downshift will put you at 5070 and 5380 rpm respectively.
Is that where you want to be?
I also needed a tuner to correct the speedo (you may not). I used this to reduce my shift points 500 rpm. I really do not need to be at redline when towing. This also helps prevent the downshift.
