why long arm? why lose the body lift, are you sure its a two inch lift? and for 37" tires I would run 4.88. However other than a 8.8 in the rear you dont need to do anything to the front to run 35".
Here is how I built my TJ and it went everwhere I wanted it to. D30 with detroit tru-trac in front, 8.8 with ford posi in rear, homemade 2" budget boost, 1" body lift, homemade belly up skid, SYE kit, adjustable uppers in the rear, removed from sway bar, 35" KM2
