On my 07 JUL 6so manual with 37's I ran 5:13 gears. Now with the '13 automatic I'm torn between 4:88 and 5:13's. I do pull a 6x12 enclosed trailer with tools and supplies for work occasionally. I am also going to add bumpers and a winch. I've read quite a bit in regards to the new engine and transmission and am still completely undecided on which ratio to go with. Don't want to do it twice. Welcome to suggestions and opinions.......

 

I'm running 4:88 on my 2012 auto with 37's and it's perfect for me. Great on the highway. Plenty of power. But I haven't towed anything yet so maybe 5:13 might be better if your going to be towing often. But someone else who tows can chime in with there opinion.
