Hey Tyler! Great to hear you're making the jump to an off-road capable Jeep! Your dana 30 front axle can hold 37s, but it is NOT recommended. Try to find a dana 44 Rubicon front axle from someone making the jump to a Dynatrac axle, ect. If you are able to find a JK D44 front axle it will be able to hold 37s. On a 3.5" lift and flat fenders you can run 37s with no issues on rubbing. I recommend the 3.5" Rock Krawler Mid Arm Flex kit if you do not plan on wheeling it a lot, but in the case you do end up wheeling more and want a "flexier" lift kit then I would recommend the 3.5" Rock Krawler Triple Threat Long Arm kit . You will need to order a new set of rims if you are going to run 37s also. Your gearing depends on what motor and if you have an automatic/manual transmission. Yes, 5.13s are ideal but some do not prefer them because the lack of power. As far as front and rear bumpers go, which exact style are you looking for? We carry everything from the stinger bumpers to brushguard bumpers. If you are interested you can PM me and list off parts you are looking at and I can make a cart and send you over a quote. Plus!
