Now that it been said that we dont need new carrier for the ones w/ 3.21 me included. 4.10s would put me back where I need to be but I am wanting a tick more for towing ability I was thinking a 4.56 but they dont make them yet my question is this how much of a difference is it from 4.10 to 4.88 to me just going to 4.10 is a big jump but so is a 30" stock tire to 37" m/t is 4.88 going to be to much for the highway and I should just stick with trying to get a set of 4.10 or go and get 4.88 I live in FL so there are no rock just sand hills and mud my jeep is most going to be on the road what would yall choose for drive ability

 

what size tire are you going to run?

 

I am running 37s right now

 

you would be happy with the 4.88s. I am putting them in my 6 speed and will also be putting a set in my auto, unless I decide to put the 410s in the auto.

 

i would go 5:13's. WOL is running 5:13's with 35's. with his 4 door..

I'm also going to run the 5:13's as soon as the shop gets me in...
