i have Zero issues with my 4.11 gears in my 05 sierra 4WD, ecsb with a 5.3, and 35" tires, if you are at a stock tire size id try and stay around 4.11, wouldnt really see a need for 4.30's, thats just my opinion though :shrug:

id highly suggest going with a detroit tru-trac, the factory g80 is a ticking time bomb, my blew up with no warning, along with 3 or 4 friends of mine, just piece of mind imho

according to who?
ive had the 4.11's in the truck for over 6 years now with no issues, 13mpg around town and 17+ on the highway.
if i were to go up to a 38" tire id definitly go with a taller gear, but 35's are perfectly fine with the 4.11's

Any body have an idea why my silverado I'm posting about here used to be able to do huge power brakes and burnouts and now it'll barely spin and it feels like an anemic v6?
