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,...

I agree on the gear change even in a 1/2 ton. It will make towing in hilly areas much more pleasant. I wwas ips also look into a custom tune from black bear tuning. They are the go to tuning company for GM gas trucks. And when you find a V-10 Ford truck 5star is the place to go! Worth every penny to do a proper tune!
