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,...

Owned three Suburbans now...3.42 4-speed half ton, 4.10 4-speed half ton. 3.74 6-speed 3/4 ton.
I continue to be amazed at how much time the 6-speed truck spends in 4th gear and 3000+ RPM.
The more I drive, the more I wish I had a higher-geared rear end, so that the RPM's in 4th gear would be a little lower...
NONE of the vehicles want to do much of anything in "high gear"...and ALL THREE are very quick to drop all the way down to 4000 RPM gear ranges- I understand that there is a time and place for that, but it seems to come too often and too quickly.
Camper: 27 ft, 7000 lb gross weight, speed 65 to 75 MPH.
Comment to the weight police...While the 1/2 ton vehicles towed ok, there is a lot to be said for the heavier springs...and more about HANDLING than PULLING...and it's sort of a maxed out/marginal performance feeling on the half tons versus a 'competent' feeling with the 3/4 ton.
