Like Brad says, the long travel arms will require longer shocks.
My advice is look close at the +2's, I know many use stock shocks but some require odd size shocks. When i talked to LSR their arms required 17.25" shocks or something close to that.
Houser makes a +1 LT design, but set up for 16" shocks. These are super heavy duty arms, and would be my first choice. I know a guy on this site that has a set of used ASR +2's, and I don't think he is asking that much for them.
There are 5 sets of +1 red LT for the 16" shocks. These are the old design with bushings instead of needle bearings where they mount to the frame. I am trying to strike a deal on all 5 sets as we speak. I am also waiting on a call back for +3's.
+1 LT with standard shocks: retail $875 Special on these 5 sets: $650 First come first serve on these, after they are gone, no more deal.
Those do look like a well put together set of arms! Some zerks are the only thing missing. I like that they're using some decent seals at the frame. If only my pockets were a little deeper, I'd be calling you to order a set of those to fit my 16" shocks!
