Is the JKS max clearance kit always necessary for 37 tires?

I did think about this, I've read so many mixed things about the zone UCA's rubbing or not on the Mickey Thompsons without spacers, but less likely to rub on the KO3's. Discount will be mounting the tires, I don't think they'll mount spacers in the event of excessive rubbing but I would want to do the spacers myself anyway so I know it's done properly and torqued accordingly. Really tho I just need it to be driveable to my garage so I can start doing some cutting

Discount used to not touch anything with spacers, I used to have to jump through hoops with my old ranger because it would rub the frame bad without them due to the wheel offset.
But now I know at least if they're already mounted, they will check the torque but other than that they won't worry about them. So you could either throw the spacers on before you take it up there, or just deal with a little possible rubbing on the way home and mount them.

Do you also trail often? If so, any rubbing with articulation or full-lock?

I'm looking into some other wheels; in the meantime though I still like the factory squatch wheels but my 1" spacers already shipped so gonna try them anyway. I believe it should result in a +4-5mm offset. I'm also leaning towards a "smaller" 37" tire too like the BFG's.

No, I haven't done any trails so I can't comment on that. When I had 35" KM3's (on stocl suspension) they would rub on the front mudflaps at full lock going up a hill or over curbs. I removed the mudflaps and the 37's with lift haven't rubbed on anything so far.

I am now waiting on my TPMS to arrive and my new Rocktrix wheels and 37 Blackhawk RT tires will get mounted.
I will see if the 1.5/.5 level kit and +12 offset will clear at least on level terrain.
I am NOT going to be too concerned with slight rub on full flex and SB disc.
I've realized I should never have wheels cranked in that situation.
I am going to have to remove the AIG mud flaps from the rock rails, due to they stick out a bit.
The BroFlap set is inbound to rectify that issue. I should be able to mount much farther back.
I'll upload pics before and after. Looking forward to getting the Superchip programmer in as well.
That will allow us to set the wheel size and do all the other mods and tunes with our devices.

No need to use the Forscan to make mods.
