Changing the gears in my suburban

One thing to consider is that as you go to higher ratio ring and pinions is that it gets weaker the lower you go...The truck will feel a lot stronger, but will actually be weaker in the ring and pinion area... So The only real fix is a heavier duty axle that will be stronger with lower gears.
