Fairly new but looking to get more serious with the local Jeep club. Bought an '08 JK X w/ 3.73 gears and looking to build it right for offroading. Would like to run 35s eventually and ARB Lockers. I know they make a Rubicon Axle Kit but was wondering if it would be better to jump up in Axles and Gears now and save changes later. I have added ARB Air Lockers, Rugged Ridge Rails & Front Bumber, Smittybilt XRC Winch, 2.5" Teraflex Lift, KC Slimlites, Quick Discos, Airaid CAI, Hypertech programmed. Got my wife the Unlimited X so none of the parts will be wasted.
