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,...

I think this is a good idea OP. Seems every answer on this forum ends with get a 3/4 Ton. Gets really really old.
You know what got really old for me? Having breakdowns while on vacation because my half-ton Suburban's rear axle failed. I maintained it religiously, checked my weights on every trip, never was over, yet I had two catastrophic failures of the rear axle. It was a lot of fun explaining to my kids why we were spending four days in Youngstown, OH and Mitchell SD, instead of places like Colonial Williamsburg, Rushmore or Yellowstone.
When I sold that truck, it was on rear axle number four. Half-ton trucks just can't cut it with their semifloater rear ends. They're not meant for heavy/long-distance towing. I have a 10.5" full floater in my 3/4 ton Burb that AA rates to 10,000 lbs.
My current trailer is the heaviest I've ever pulled, yet it's also the least stressful to tow. No sway, no push-pull from semis, just a pleasant, stable ride. Eagle-eyed readers will grasp the enormity of that statement.
I'm just trying to share my experiences, hoping others might be able to avoid the problems I had, trying to do too much with a half-ton.
