Xtreme recon package 392 - 35s, lift and gearing

[ascuro]

No, I was asking if Jeep going from 33" tires to 35" tires is what is changing the approach, breakover and departure angle's along with the ground clearance?

Yes, of course it is. Larger tires along with the lift.

well the 2021 392 has the lift already, so I am suspecting that the Recon just has 4.58:1 gearing and 35" tires and that is the only upgrade from the 2021?

Not sure if anyone knows if the lift will apply to the 392 yet (I'm guessing probably not). 4.56 gears (on 35s) seems like a bit of an overkill for the v8 as well to me.

Has anyone done the math with the stock 392 with 35" tires to see if all they are doing is putting 35" tires on 8" rims and calling it an Extreme Recon ? and change the gearing to 4.56:1 ....

this is what I’m trying to figure out - what is the change to the suspension when it comes to the 392? Dealers don’t seem to know as they’ve had no detailed communication on it.

seems a lot if it’s just what you note above.

if so, then why the same price as adding it to the Rubi? Because Jeep?

Because peole will pay for that cool name even if its usles for V8.

FYI - updated original post with more comprehensive list ie has tailgate hinge reenforcement, spare relocation kit and upgraded brakes (wonder if 392 has this already)

I read something yesterday in a write up that the 1.5" lift was on the standard Rubi and the 392 stays with its 2" from the factory.

" To compete with the Bronco's Sasquatch package, the Xtreme Recon adds 35-inch BFGoodrich All-Terrain KO2 dirt shredders mounted on beadlock-capable wheels and 4.56:1 gearing for the axles. A 1.5-inch suspension lift with retuned dampers will support the Wrangler Rubicon, while the 392 makes do with its standard 2.0-inch lift. "

Car And Driver Recon Package

Basically on the 392 no lift and 1/2" more on the standard Rubi for the recon package. Basically 392's get 35's and maybe gearing. If the 392 could safely handle 4.56 on factory axles well then there was not much of a reason not to put 4.10's on the 392 Rubi. I have done the math and have concerns the JL axles are up for the task with lower gearing than 3.73 unless you never push hard on it. Well at times I will push it hard and I want it reliable when I do.

In 4 auto 4.71 first and 4.56 basically 10,100 ft. lbs. on the ring gear and axle shaft's through 2 shafts 5,050 through each. That's a lot for a dana 44 set up and that's in high, in low it would be 13,700 through each shaft. Basically bind up on the rocks and push it shit will break pretty quick.

The M220 is said to be improved and basically the gear set is said to be as strong as a Dana 60 but no hard numbers that I can find. A dana 60 gear set is rated around 5,500 from what I can find. That's a lot more than a JK 44 rated at 3,460 so I question the real number on a M220.

And they both still only have 32 spline shafts however the gear should be the weak point. It would be interesting to mark the shafts do some hard launches with a 392 and 4.56 gears pull them and see if the shafts twist.

At the end of the day a Gear set and install for me would be about $800 and a day's work, 35" tires would be about $1,500. So even with tire relocation no where near the 4K price and I get to pick my tire.

On mine I have not decided on 35 VS 37 and if I would re-gear even with 37's. I will eventually change to one or the other. There are reports that performance is not drastically changed from those that have done it.

If there’s no modification to the suspension then it really doesn’t make sense to have the same price point.

anyone seen anything on the wheels - are they still 392 bronze unique?

I guess you factor in the included rear hinge reenforcement if you already had that $700 item on your build.

it still may appeal if you’d be paying for the install and want the warranty coverage.

i’d disagree on the useless. If you’re going larger tires, especially 37s, 4.56s (and even 4.10s to some degree) will help gain back some of the low end despite all the torque available right of idle.

the bigger gear issue to me is compression braking … not nearly as big a deal in the rocks out west, but on the east coast, having that lower gearing on steep, slick downhills can be critical to controlling descent when brakes aren’t an option.

So will the 392 be available for '22 MY given these changes?

I'm getting ready to put in my order (decided not to take an ordered '21 from a dealer in Kansas after hearing this) but wasn't sure yet if they're actually going to continue production through '22. And then there's the color question.

Yes. The 392 will be available for 2022 and likely beyond. We are at the end of 2021 MY. No way Jeep spent all the engineering costs to build 392's for less than one model year. Makes no sense. Bean counters would go nuts!

If I were you, I'd wait for the 2022 orders to open before placing an order. Look what just happened, the Xtreme Recon package was just announced for the Rubicon and 392: 35's and 4.56 from the factory, available in July (almost end of MY 2021). Don't worry, don't panic, be patient, the 392 will be around for at least MY 2022 and I would bet at least through the JL model run (5 more years?). I may wait until MY 2023 to see what the mid-cycle refresh looks like before ordering a 392. And by that time, the hype will have settled down, and hopefully I will not be forced to buy all the add-ons I don't want (body color hard top. leather interior, body color flares).

Bean counter argument is a good one for sure. Then again, demon.

I actually would option it the way they did other than I’d prefer tan interior option so no issue there. But yeah id absolutely want the 4.56 gear and 35’s option. With 2” of lift I could gut the fenders and roll with 40’s for moab days, keeping it stock otherwise. I don’t care about uconnect 5 but if the mid refresh is that huge I’d just trade in anyway.

Either way, keeping my gladiator and 2 door JL, so not having to deal with a trade this time around will be nice. Hoping for more color choices though

 

[dalema]

I added it to mine with no issues. Got CC'd on emails from my dealer communicating with Sellantis.

@Outrun - any chance you can post a pic of your build sheet (or just the recon package part)? Or anyone else who has been able to add it to a 392 @PaulNY

This is from the Rubi V6, so interested in comparing ……
