21 Jeep 392 XR
I picked up my wife's new 392 and went to modifying it. Let's just say I like to push the limits. We are Just getting started!

Nice! (y) Looking forward to seeing the stance of the lift when it’s on the ground!
 
Wow. 42s! Looks really good.

What corrections have you done/will you do to the suspension geometry and steering? How does it drive?
 
How about some pics of it actually sitting on the suspension? I suspect it's going to take a lot more than a 4.5" lift to yield that kind of clearance over 42s with a settled suspension.

Yeah, looks like a sweet a$$ mall crawler, on 42’s 🤟. Our other 392 is a mall crawler, on 35’s, and soon to be on 37’s.

The XR is a silly package if you’re off-roading on 42’s because you’ll need to swap axles, replace or delete your spare tire carrier, strip out or replace the fenders so you can go over a rock… and that doesn’t even begin to cover the steering upgrades you need to turn 42’s, off-road, when you’re aired down… but the same could be said of any Rubicon.

You are so correct. I learned years ago that if your are going to rock crawl on a dana 44, 37" is about the max, even if you upgrade to chromoly inners.
I have a LJ Rubicon, once I went from 36" tires to 38"..I started breaking.bThat led to ProRock 60's and Hemi 6.1 swap and Genright coilover suspension.
Even with ProRock 60's (hi pinion, reverse cut gears...weaker by design) and now 42" sticky's, I break ring & pinion.

But for just $25k, you can go with Currie Platinum dana 70 option. However they are hi-pinion, which means reverse cut r/p gears....more clearance, but not as strong as a regular dana 60. Always a tradeoff.
 
Currie is good, light weight. However any hi-pinion design is weaker by design.
Dynatrac is also good. I'd call company and discuss what you want/need.
Thank you! I have a whole laundry list of stuff I want to do to make it rock solid with 40's. I figure it will be $50K plus when all is said and done.
 
Not only did I break ring and pinion gears in h-pinion ProRock 60's with 42" stickies, Hemi 6.1...also broke an ARB locker in rear. Rear seems to break quicker than front.
Jeep was built, suspension set-up, to run 44" Pitbull Rocker tires (44x1950-17). Way too large for dana 60 axles.
 
A lot will depend on how hard you drive your Jeep. Are you really going to bash a $100k plus Jeep in the rocks.?
My driving style, when I was younger was...You will make it over/up the obstacle. Pedal on the floor if necessary. I have chill'd out a little 😂.
 
For most the Currie Platinum 70 (may be lighter) or Dynatrac is more than enough with 40" tires. Dynatrac is up to dana 80's now.

Mild rock crawling and mountain driving. No bashing lol. I like high quality parts and strength . I'm single, no kids and good job. Gives me something to do.
 
You'd be fine with Currie Platinum 70.
