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,...

The first thing I would do to that suburban is call Black Bear and get a tune. With a good cold air intake and a tune you can gain ~20 hp/tq and have modified transmission shift strategies to keep you in gear and lockup longer. Add gears and it would do well....plus you may need a tune for the speedo anyhow if you do gears.
I was towing 7K tall trailer with a 99 Tahoe that I heavily modified (in my sig) and I just realized it could do it but it was working too hard for my driving style. Had to upgrade trucks....still have the Tahoe.
