rear coil recommendations

[shogan]

Zone 4" installed, front is stock shocks, rear currently is ICON 1.5 w/ Zone 2" spacers.

Going to add Bil 6112's on the front, likely set ~ +0.8" (so net ~5" on the front)
I'd like to get rid of spacer in the rear, and wind up with slight tail-high stance.

My simple math makes me think I need ~4" in the rear to wind up ~ 1" tail high.
I'm intrigued by the JT progressive coils. Am I reading previous post right, and JT coils, used on our RAMs, give about an extra inch over the stated JT lift?
So something like the Synergy 3" JT coil, or Clayton's 3.5" coil would get me where I want to be??

@ram1500rsm - I think you're the expert on JT coils?

Remove the rear spacer and do the 5" rear box kit from Zone. Gets rid of the rear spacers and replaces it with a full length coil. Also comes with the other other parts needed to lift the rear to that height.

I'm curious if your ICON coils actually net'd you 1.5 inches? They gave me just under 1 inch after settling and that's with an empty bed. They were super creaky, too--had to put in some Eibach coil sleeves to quiet them puppies down. Not impressed so far.

I didn't want to have to use spacers but looks like I'm going to have to throw in some 1/2" McBays to get that height back.

My truck must just be heavier overall because my Bilstein 6112s set at 2.8" only gave me about 2 1/4" lift in the front. Interestly though, my pre-lift #'s were among the highest I've seen anybody post 37 1/2" in front and 39 3/4" in the rear when completely stock, and only about 1/4" Ram lean.
