I changed my axle ratio on a 2002 (?) 2500 Suburban from 3.73 to 4.10. Made a noticable difference towing a circa 8,000# TT.
Hurt my unloaded gas mileage a bit, but since the primary purpose of the vehicle was a tow vehicle, it was a good tradeoff. I was close to out of warranty in any case, but asked the dealer about it and they told me they would not warranty the new gearing, but that the change would not void any other part of the powertrain.
