MPG's 2013 jku 6 speed, 4.10's and 37's?

2013 jku 3.6 4.10's and 37x13.5 17's Just curious if anyone is running the same setup and if so what are you getting for MPG's? I ordered a procal but it hasn't arrived yet. Currently my computer is claiming 11.9mpg as my average. Just curious to see what others are getting.

Thanks

Don't expect much. Mpg on 37's seems like a less than 15moh assurance lol

13.759 is you calculated mpg. i know some with 4.88s see just under 16. may be worth it to regear, plus it will help more on trail

I hope you have or are planning on sleeving , gusseting that front axle soon. A 4.88 or 5.13 gear set would get you a little performance possibly mpg back.

theres some great write ups. you may want to consider upgrading axles eventually to something beefier.

2013 with 4.10's and a dana30?? How did you swing that, I thought 3.73 was the lowest gear set for a non rubi?

I originally went to the dealer in search of a new rubicon. When I got there on the showroom floor they had a white (color I wanted) lifted sport with dealer installed 4.10's, mopar 4 inch lift, mopar light bar with hella fogs and the 37's. The salesman told me that they built the jeep to showcase the mopar aftermarket parts catalogue. I talked to the mechanic at the dealer who built it (big time 4x4 jeep guy) he had also trimmed the pinch seem (filled it and painted in nicely) and also added a new exhaust section to clear the driveshaft during flex. I got the sport for less then the original sticker price before the mods. I just couldn't pass up the deal / and or wait for a Rubi. The money I saved on the Rubi will be going into the sport. Just ordered stubby/winch, hi-lift, discos, recovery straps, and a procal. Once I find someone that can weld I'm going to have the D30 taken care of. Then I will get lockers, etc.
