3.21 gears - not that bad?
#61
I verify 2400rpm @70mph for 3.73/5speed auto.
Although my math tells me 2275 rpms for a 32.1 inch tire? Where's that 125rpm difference at? I know there's some sidewall bulge but at 37-38 psi?

2013 with 6 speed and 3:21's.
Really wanted the 3:73's, but almost impossible to find in my area. Bad enough the dealer had to go 110 miles to get my 6spd Dozer.
It turns out, that the 3:21's aren't as bad as I thought they would be. Mostly have the Jeep for the beach and snow, so the move to steeper gears is near the bottom of my list. MB TKO's and 265/70r17 Grabber At's are coming

Had an 07 JK with 3.21 gears and a 6 speed, now I have a 13 JK Rubicon with 4.10 gears and a 6 speed. I liked the way I could drive 75 MPH at 2100 RPMs in the 07, but there is a lot more power with the 4.10 (of course the newer engine could be a big part of that). I'm not used to changing gears yet, 1st gear seems so short now, 3rd gear feels a lot more powerful, and 6th gear makes me check the gas gauge. All in all, I like the performance of the 4.10, but I miss my gas mileage.
