I have a 2012 Silverado Crew Cab 4x4 with the 4.8L and I'm wondering what's the best gears to get for towing, I live in North Dakota now so it's very hilly out here and my truck has a major struggle going up them... very annoying because I basically have to floor it to make it up without dropping 10mph.. so I'm trying to decide between 3.73 & 4.10, I know 4.10 will be high rpm on the highway but what's will make it easier on the motor and tranny for hauling? Thanks

how much towing are you doing? and how heavy of a load?

I'm only hauling a 2 seater polaris RZR on a flat trailer .. not a lot of weight at all only weighs roughly 1,300 lbs by itself . But I plan on driving back down to Texas next year with it loaded down and don't want to struggle the whole way because that's a nice 23 hour drive

With a 4.8, 4.10s minimum. You won't lose much gas mileage and it'll make a world of difference.

i know those 4.8's like to rev. im surprised. I just went down 9 hours to WV to ride, i had my 03 1500 with 33's and 3.73 gears, and a snow mobile trailer with 2 quads, tools, and around 50 gallons of gas and it wasnt bad.

Iv driven to Texas and back about 5 times now and it does not like the hills, I have 33x12.50r20 tires, iv always wanted to change the gears but since I just got this new toy it really makes me want to change them, it's horrible with hauling.

Have 4.8 5 speed with factory 3.73s. On the highway with 285/70/17 tires its revs at 2100-2200 rpm at 75mph. I wouldn't upgrade to 3.73s make it worth while and do 4.10s will bump the Revs up a little but not horrible

I have the 4 speed but I'm going with 4.10's anyways , been hearing people going with the 3.73 and wishing they went to 4.10 instead
