You guys that are running big lifts on your 08 or later duallies what are you guys doing to lift the rear. Every lift I look at for my dually says not for dana80 rears. I was going to buy the rough country 4 link 8 inch lift kit. The ubolts in the kit wont fit my rear end. Are you guys running stacked bocks in the rear or one big block. Or should I add a few leafs to the rear spring pack and have them re arched. I'm also looking to run some sort of traction bars or ladder bars in the rear.
