As i stated in the title I have an rcx 6" lift and a 1" rear spacer. Now I am getting my bilsteins 5100's installed tomorrow and I am trying to figure out what setting. Should I go with the 1.4 or the 2.1? Thanks gents!!

With a 1" rear spacer you'll probably need them at 2.1" to be dead level. 1.4" if you want a bit of rake. But the easiest way to find out is to go out and measure the fender heights of your truck as it sits now. You'll find out how much rake you have and then know how much you need to add to the front to make it level.
Are you half an inch lower on the front or on the back? If it's the back then that's fairly typical.... Lots of Rams have that for some reason. If it's the front then I'm getting something is either installed wrong or possibly bent.
