What size tires? Did you stick with the 285s or go bigger? I’m wondering how big I can go once my stock ones wear out.

I was also looking closer at the axle height. Looks like I’m going to have to lift her a bit and get those axles off the floor (relatively speaking).
@DocSkip did you do any lift kits? Might be able to lend Back2Jeep some insights on the mods you did for your ride.

I went with the same tire size, I'll post pics of the perellis I went with when I pick it up. Hopefully today, fingers crossed.

I've never tried to put a lift on a vehicle with an air suspension, is that even possible?

Yeah, you can lift it but have to be careful with arm placement, etc. I’ve seen it done in some Rams with air ride. Not easy, but doable.

You guys were right, the GW does come with roof crossbars, they are in the cargo area under the mat. Oh well, now I have a backup set too LOL Btw that area back there looks perfect for when I install dashcams and want the battery power for them tucked away. I'll try and remember to take a pic tomorrow.

In the cargo area I had a foldable cargo cover, netting (included), and a cargo mat that I had ordered (extra). In the tire jack area under the mat there's a tow hook to connect to the receiver, and a small funnel to put in the gas tank for filling with a jerry can.

Here's the Uconnect system version mine was on when I picked it up:

My new tires aren't going on for another 2 weeks, bummer. But understandable. the service dept has been booked out 3 weeks in advance for at least the last year.

There it is again, the Build number S21B.5 versus another person's reported S21D.5. Nothing like seeing it in the photo. Thanks!

My car was built at the end of April, I can lookup the exact date if that helps.
Thanks, no need as the key was the UConnect version for another thread on the forum. Just trying to get a bead on which version is the 'current' version and if it is different for Wagoneers vs. GWs. Either way I think we are all getting a big update in June. Looking forward to it with hope and trepidation. 🙏🙂

I know they changed the pistons in the 392 so you can’t do nitrous. Hm. Will have to see if they did same on the Wagoneer line. If not; I see a supercharger in my future.
I didn't know about the change. Installing a supercharger would add a lot of horsepower and a need for a bigger radiator for cooling. I suspect changing the engine block from aluminum to steel with rebored oil and antifreeze for added extra cooling. They could rebore with a titanium sleeve in each cylinder for added strength and sleeve replacement if ever needed. I haven't calculated horsepower improvement with NOS, but I am easily leaning on 50 to 100 HP before massive engine failure (BOOM) happens. I wonder what NOS vs. Supercharger is in the total cost?:unsure:

The guys I know that have tried the NOS on the JLU 392 are blowing the piston rings at anything over 6 psi - that they were too close to the top and light weight for the boost. I remember one of the 392 guys that works at the plant saying they had swapped the pistons and some stuff on the 392 - that it’s def not the same engine as the others but naturally now I can’t find it. The plant guy said youre good to 600 hp on the JLU 392 and after that you have to swap. He says modern Muscle extreme makes drop ins, so that’s good to know.

Wish there was a tech or guy at the plant that I could trust that could tell me what the difference is, if any, in the GW 6.4L 392 vs the JLU 392 Vs even the GC 6.4L. I’m not ready to start breaking ours down yet. 🤣🤣
