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,...

If your 2008 Burb still has the 4L60E in it, you probably don't want to re-gear it so it can tow in OD, because the OD gears in those transmissions are reportedly weak, or so I've been told, and read in multiple places such as this site.
Another thing you do NOT want to do is regear and end up turning the same RPMs in OD as you were in direct before the gear change. You've gained nothing from a bunch of work and expense.
