I have a 2012 JK is 12JK with a 3 and a 1/2 inch metal cloak lift and 37x13.5 tires. The Jeep does drive amazingly well on the road, very capable rig off road as well. I would like to get a little more clearance thinking about 4" Springs and up grade shocks. Possibly some steering upgrades which I believe is needed for these heavy tires. My question is will I have to make any other adjustments to my existing lift kit and will I need a realignment?
