Had 1/2" spaces installed with 37's. Seems much less wander then my 2019 Moab with similar setup (mopar 2" lift and spacers).

Has anyone regeared yet? (i posted in gear section). I want to go to 4.88's but shop not sure what pars to get

I finally got out to flex the Jeep with the Nitto 35s. I have about 1/2” clearance. This is with no body or wheel spacers. All stock. I would definitely need to adjust something for Nitto 37s to avoid rubbing when stuffed. Maybe the KO2s in 37” would be ok?

Installed front and rear Mopar Sway Bar end links. New links are about 1” longer than stock. Tricky, took me 2.5 hours. Probably longer than it should have given I was improvising a little with my tools and working with the Jeep on the ground.

Tried to install the Rubicon Express shock extensions. A spacer was slightly to wide for the shock mount. Will need machining. Set an appointment for install by 4wheelparts as I ordered the parts from them.
Also considered looking into front and rear control arms but from this image of the 392 suspension from EJS, looks like the control arms might be bespoke to the 392. In which case we will have to wait for the aftermarket to make one specifically for the 392.

Still waiting on the Mopar LCAs. The progress continues.

Not surprised at how well these 35x11.5x17 Trail Grapplers tuck in there as these were one of the sets of tires that the 392 mules were seen on.
What is the overall height of your tires? The 37x12.5x17 K02s are about 35.25”. Also, since they are 12.5 inch wide, you will need wheel spacers. You’ll also definitely need the Mopar extended wheel carrier as Willy’s Commando has reported from trying.

I'm right at 35.25" on the Nitto Trail Grapplers in 35x11.50R17. That's what I measured on the spare (not supporting weight), and also 35.25" on the rear-passenger tire when measuring front-to-rear. I'm currently running at 35 PSI and the top-to-bottom measurement is 34 3/8" on a tire supporting weight.

I’m about 36” front to rear and 35.25 top-to-bottom on rear right tire at 34-35psi.
