Not that this will matter or that most will listen but chasing articulation is a fool's errand generally. I see builder after builder claim high amounts of articulation as a selling point or some expression of something. The problem with that is there are reasonable limits to build to and once you get there, every extra inch of travel compounds issues. You want more than about 12" on a TJ, get ready to drop the belly skid down or get a very high dollar rear driveshaft that can handle the droop with a low pinion rear end. Want a high pinion 60? That's a good way to practically require one.
You should leave the shop alone and learn how to pull the springs and cycle the axle with the shocks in place. There is a thread on here on how to set your bump stops. Read it, learn it, practice it, and then do it some more. Before long it will all be second nature and more valuable than what most shops will tell you.
With regard to the one I put up above. The upward travel limit is the small cross section of the Savvy truss on the front axle. It hits the oil pan at the front of the engine. Do we need more up travel than that?
Once you figure that out and learn it, that knowledge can be used to instantly evaluate other things. Things like those giant horrid trusses on front axles. Put one of those on and it will run into shit long before it should.
