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,...

Recommending an upgrade to a 3/4 or 1 ton truck is "offensive" but apparently it's acceptable to recommend an expensive engine overhaul and blower?
The gearing change is relatively easy and inexpensive, especially if the OP can DIY it, but an engine overhaul and blower kit is going to run you SEVERAL THOUSAND DOLLARS if not more.
Even after that expensive overhaul and blower, he still has a 1/2 ton transmission, a 1/2 ton driveshaft, a 1/2 ton rear axle, 1/2 ton springs, 1/2 ton frame. All of that needs to be upgraded to handle the extra power from the blown engine, and he may still need the gearing change after all is said and done.
People consider gear changes because they feel there is a deficiency in their tow vehicle. That deficiency is in power. That deficiency is caused by a heavy trailer, which while it may not exceed any limits on paper, is still a significant load on the truck that could be handled better by a heavier duty truck.
Heck, at page 6 I don't even think we've ever been told what trailer he is towing, or what it weighs! Yet the "Anti-3/4-Ton Police" are here in force shouting down anyone that dares recommend upgrading the whole truck rather than just the axle gear ratio.
But again, it's perfectly fine to tear the engine apart and put a friggin' BLOWER on it?!?!?
Ultimately, it is the OP's choice, and it does not hurt to have all the options laid out on the table. Maybe, just maybe, the OP will see something that he had not considered before?
...but nawwwww, let's just shout down anyone that doesn't answer the OP's questions exactly as asked...
