Anyone with a JKUR running 5:13 gears, a RIPP supercharger, and 37 in tires? My JKUR has this set up currently with an automatic and 35 in tires and set up is great. The reason I ask question is because I am thinking about going up to 37 in tires when my 35's wear out. I am wondering what power will be like. I will be only adding 8-12 lbs total by going from 35in mt Mtz's to 37 in mtr kevlars or km2's. I am getting ready to put on high altitude pulley which the added power should make set up with 37's feel like set up with 35's some input would help.
