I am thinking of changing my gear ratio from a 3.73 to 4.10 on my 02 Avalanche 2500 (8.1L). The towing capacity is 10400# with 3.73 and 12000# with 4.10. It pulls OK from GA to FL (all flat), but I don't like the feel in the hills of the Smokies north of here at 16500# GCWR.
Anyone ever done this? I expect to gain a little efficiency when towing (lose some when not). Any pros and cons or advice you can give? Would increasing my tire size effectively do the same thing?
Anyone know what the weak link accounting for the difference between the towing capacities between the ratios (assuming the trans or load on the engine).
Here are my weights from my last trip if that is helpful. https://www.screencast.com/t/3PUjNilnDOR
Curb weight of the truck is 6353#
