So after reading all of the posts here, it sounds like 5.13s are the way to go if one is to stick to 37's. What I couldn't find in here though was if I were to re-gear to 5.13s, will they fit into the stock Rubicon axle diffs? Also, I take it that I need to replace both front and rear from stock right?
I'm currently running Nitto Mud-Grapplers. 35x12.5x17 but in the next couple of years I'm going to be switching to 37 Nitto Trail-Grapplers and I plan on staying with that size and tire.
I live in Wisconsin and my wife and I are planning on driving the Jeep to Lake Tahoe in a couple of years and next year we are going to be driving to Moab to the Easter Jeep Safari. I usually am allowed one or two upgrades a year so long as the price is right and/or I can make a really good case as to why I want the upgrade. I just want to ensure I'm getting all the info before I buy something and have a shop do the work for me. Unfortunately we here in the mid-west don't have awesome off road shops like in the west. Most of the work I try and do myself but some things I just need a real pro to do it for me.
