Finally got my setup finished this month after accruing parts since last November:
Ironman 4X4 2.5" front (0-110 lbs) & 3" rear (440-880lb), with their forged UCAs. Sold the Sport wheels with SL265/70/17 General ATXs, and got my dream set of LT255/80/17 Wildpeak AT3Ws mounted on 5th Gen SR5 snowflakes.
Supporting parts: EimKeith PCK, OEM OTREs, garbage Moog LCAs with eBay cam bolts, Amazon front SB relocates.
No diff drop installed, the angles are pretty good looking (much better than my 3rd gen), the CV boots are still holding up, so far. Found a thicc Addco swaybar on Marketplace to install with new Proforged 2nd gen links (eventually).
Overall, very happy with the setup, and everything's solid. The alignment came out spot-on. The skinny LT Wildpeaks feel like they have less resistance on the road than the old SL General ATXs. I experience some rubbing on the front fenders in reverse, not fully-locked. My 3rd gen is the wheeling rig, and this is the camping-hauling-DD, and eventual dad-mobile. Planning on a front end overhaul in the 3rd gen in '22 with much beefier components.

After:
Much easier with 2 people getting those thicc rear springs in with 2 people, axle fully-dropped:
I just wasn't satisfied with the 265/70/17s after the lift, and I've always been a pizza cutter fanboy:
