I'm getting new gears next week and torn between 4:56 or 4:88 gears i currently have a 2012 JK 6 spd w/3:21 gears and 305/70/17.

What do you think ?

 

Also, unfortunately used 80% highway/city driving and only 20% off road.

 

I'm in the same boat but for the price difference I'm gonna go with the 4.88 the price here was around 500 difference

 

I got a 2012 w/ 6spd unlimited and 35s. Im thinking 4.56 but thats me

 

Go with the 4.88's.. Many will argue because of the benefits of the new motor, however a good modo to follow is, "don't fear the gear!"

 

i'm doing lift, wheels, tires, gears in the next 3-4 weeks and i'm going back and forth between 4.10's and 4.56's. i wheel 1-2 times a month and I think that for most this is about how much they actually get out. so if you do the math; for the avg jeeper its more like 95% on-road and 5% off.

 

For your situation being you have a 2012,
6 speed and do alot of hiway driving..... I'd deffinately go with the 4.56
Good luck

 

I've been running 4.56's for 6 months now.. Absolutely no regret! I feel it's the best combo.. I'm have a 2012 unlimited on 35's.. I do 80% highway as well.. Some hills, which it pull in 6th gear and hold 65mph and can even accelerate if need be.. My 3.21 would have had me down shifting just to hold 60.. Best of luck with your decision!!

 

I just did mine last week, very happy I went with 4:88. I have a 2011 with 6 speed and am running 35's.

 

OP has a 2012 so he's in a different situation then you with a 2011
