I feel like I should be posting this in my Mustang forum and not here, but I thought it would be fun to hear other people's experiences. I have a stock 2012 JK with 3.73's and auto. The only mod is larger tires, 285/70/17. My wife and I recently moved from Colorado to New Jersey and I am enjoying the additional power our vehicles make at sea level. Yesterday, I was out on Long Island and while sitting at a red light, decided to punch it when the light turned green. I was way out near the eastern tip, and the road was empty. To my surprise, our little JK lit up the rear tires and absolutely roasted the 285/70/17 BFG Muds. Wow. No axle hop or sideways or anything, just a nice, smooth clean burnout. I know a lot of people love and / or hate on the Pentastar but wow, what a stout little motor. Not that burnouts are what our Jeeps are made for, but can you break traction in your JK?
(3.6, 3:73's, on 32's at the time) the one time I did it, was when my friend pulled up next to me and wanted to race. I burned out into half way through 2nd gear and smoked him lol very nice controllable burnout. BUT I DIGRESS.... Now I'm on 35's and I don't think that burnout thing will ever happen again.

Our 012 with 4:10 and 35"s on steel, still can burn rubber half pedal, auto. When we bought it had the 32"s and 4:10 stock it could fry the tires. we did order the 4:10s though as the rubi auto then/now? were an option and stock was 3:73. the auto first gears is fairly low. you could about compare it with say an 011 with 4:10 and the 012 same gearing is more like in effect 5:13. Of all the new things 012 brought to Jeep. I think the auto was the biggest upgrade.
I have done it. 4.10s, 32" Firestone M/Ts and nothing else changed.
