That's what I suspected. Probably a non-issue for all but those who plan on using the full capabilities of a Rubicon.
Once the clutch is fully engaged it shouldn’t really matter how much you beat on it. Where problems could arise is using 4 Auto in a situation where it will be constantly adjusting clutch pressure, like beach or desert track driving. This could create a lot of heat from slippage. You’d be better off running it in 4Hi then.

COST.
Monthly payment threshold. I'd have jumped on ir. It is not weaker nor is it new technology by any stretch and is not weaker.
700 bucks on a $55k plus vehicle?
And it seems like a lot of people have interest in it.

55k plus? Got my overland cheaper and for a 2020 it was loaded. You must be considering only msrp for rubicon etc.

this is the reason I tracked my 2021 JTR, which was the only one I could find in 2 months search, in transit to when it landed, not to mention the 61k MSRP vehicle was sold to me for 53k (leftover dealer 2021 stock?)

too easy to not sell my 2 yr old 2020 Sport S Max Tow for more than I purchased and pick up a new JTR with that great transfer case option

If you do a lot of pavement driving in poor weather conditions then I think it makes a lot of sense to get the full-time. In areas that are subject to freezing rain - this could save you from a bad experience when conditions change quickly at highway speeds.

That said - I don't have it in my truck so I can't speak to how this specific system handles. (but I also don't regret not having this system) I will say that having a vehicle that is 2wd until you shift into 4wd does make you less complacent in bad weather driving in general I believe. As long as you remember the conditions you are driving in, not an issue either way.

Yeah, but they don't make many dedicated winter tires in the stock Rubicon/Mojave size, and none in my aftermarket size. Of the two stock size (285/70/17) winter tires I see on tire rack, one is indefinitely out of stock and the other has 1 tire available.
Nokian makes excellent winter tires in - roughly - 31, 33, and 35 inch diameter (converted from the metric). They make tires for cars as well, but their best winter tire for trucks is the Nokian Hakkapeliitta LT3. Whether or not they have any in stock is another issue. We've been running these tires for years in snow country, and swear by them. I chat with a guy who is super-happy with the 35-inch Nokians on his Ford F250 diesel:

Guys, the "safety factor" a lot of you are talking about is non existent with MT or all season/summer tires. If you are concerned about safety and think a $700 AWD option will help, you are wrong.
Do not rely on 4H auto to prevent you from an accident. Get tires appropriate for your driving conditions. AWD/4H Auto is useless if the tires are not appropriate

It shouldn't be an issue ever. Clutches don't wear when they are fully engaged or disengaged. If it doesn't fully engage and slips there will be trouble. But I've never heard of this problem.

Also,, they use it in the 392 as standard equipment. I don't know if the 392's or 4xE's SelecTrac transfer case is the same as ours. But both of them put out 75% more torque than the Pentastar.

I would be curious to know if its the same transfer case or something beefier.

You are very right and very wrong.

There is no substitute for snow tires. And having snows combined with stability control will reduce the benefit of AWD.

But until you have driven a vehicle with a good AWD system that is rolling on real snow tires you haven't experienced what good snow traction is.

My wife's AWD Volvo is better in the snow than My Mojave is on the factory Wildpeaks. Unfortunately the Nokians I want are sold out for the winter. So I wait until next summer. And buy them then.

I don't have to do that because I will end up in a ditch with the driving I do with AWD and snow tires.
Try a set of Bridgestone Blizzaks and let me know how you like driving in snow conditions.

No, I am agreeing with you.

AMG 4MATIC on Bridgestone Blizzaks. Tested in deep snow, sleet, rain, black ice. Even these slip a lot on black ice so no AWD will help. Although summers would have probably sent me in the guardrail

Or that they know how to switch into 4H. Well that's not really what it's for. Selec-Trac shines on wet roads and ever changing roads. From snow to drive pavement in a matter of seconds. Those conditions you set it and forget it. Selec-Trac is by no means meant for off-roading.
So there's no misunderstanding, I'm not saying don't get it. I know what it's for, and agree it would be very useful in those situations. But for all of those who have trims and packages where it's not available, it's not the end of the world. But we (those of us with engine, transmission, or trim packages without selec trac) do have to know when to shift into 4HI to get the benefits, and not slide all over the place in 2wd. I'd definitely get it if it were an option on the manual. The diesel guys would get it if it were an option on the diesel. But it's not, so we all have to make do with the part time system. Which does mean shifting back and forth between the two. I'm just pointing out that even with the part time system the JT is just as good on the snow as full-time systems I've owned. But it takes more work. For some combinations, selec trac isn't an option, so just pointing out that all is not lost in the snow because you don't have it, you just have to get familiar with the T Case lever.

At just a quick glance. It's not available on any manual, or on Base Sport or Willys Sport, or on any diesel. So folks with those preferences in the snowbelt have to become very familiar that transfer case lever.

My Rubicon was under 50 as well, but no where near fully loaded. Just CWP, hard top, bedliner, and leds

Got it.

Yes, no amount of mechanical wizardry can make up for poor tire to road interface. I used to run track days with my Subaru STi. It wore R type summer tires most of the year, though not the semi-slicks you see now.

I got caught out in very slightly snowy conditions a couple of times and it was terrifying.

With a set of Michelin Arctic Alpens it was a beast.

I remember the first time I drove my first Subaru wagon in the snow. I had a set. of regular but skinny all seasons on it. I felt invincible charging up my driveway. Then I slid into the back yard when I went charging down it. My first lesson that 4wd doesn't help you stop. Ha.

Its also beneficial if you have a bit of a heavy foot in the rain. Around town if I'm pulling out onto a Main Street from a side street I can punch it and the truck just goes. In 2H, the inside rear wheel begins to slip and the traction control pulls power. 4A eliminates all that drama. This is a situation where it helps you when even 4H won't help.

It sounds like a pretty specific use case, but in general if you want to turn and accelerate, it helps.
