so im new to the jk game ive had my 07 unlimited sahara for about a month i got it with 15,000 mi on it. But Ive had a cj7 on 40's that I built for a few years until i sold it last weekend which means ive now started another jeep build. I have a 4"rc lift and 37" bf goodrich mtr's with kevlar on the way for my DD build. any opinons on gearing tho for the 37's i have an automatic. ive read 5.13's but i think its alittle much.

 

5:13 is what most guys go with for 37's and a 6 speed. For an auto most go with 5:38.
