If you just add a puck or taller springs your total suspension lift could go over 3”. Then you would need an SYE (for a non-Rubicon) and a DC driveshaft and adjustable rear control arms.What is the reason for the body lift over just an equalivant puck lift or taller springs? Also why ml for the same reason? Puck or springs will lift the transfer skid without all the extra hassle.
So if you want to fit bigger tires without all that trouble, a small body lift will work. The body lift also has other advantages, like making room for a tummy tuck, making room for tucking the gas tank skid, making more room for your larger spare to fit above your rear bumper, et. Al.
A MML can help with driveline angles after a suspension lift. It also gives more clearance at the oil pan.
