392 has that stock…. Non 392 I agree with the XR package BTW.Personally, I bought the XR(392 or 3.6) for the HD M210. Thicker tubes, cast knuckles, etc.
Just makes the decision of 37s that much easier.
Yea, HD tubes being 10mm, it's more stout than the Ultimate 44, which is about 8mm tubes. And ultimate 44s are rated for 37s I believe.392 has that stock…. Non 392 I agree with the XR package BTW.
Gato, side topic. But sort of related to the XR, did your JLR not come with a skid under the FAD module? I ask because mine has a skid under it from factory.If you are pending $80K on Wrangler, why not spend 5% more and get 4.56, 35s (that can be readily sold if you go 37s), stronger axles, tailgate reinforcement and and spare tire relocation (again helping with 37s) and the wider fenders to keep 35s or 37s road legal?
I think this thread should be asking why is the XR not standard on the 392.
Things not stock on the 392 is 4.56, tailgate reinforcement, spare relo, 1/2“ wider rim and small KO2 315s instead of 285s, mopar shocks. Everything else is stock.If you are pending $80K on Wrangler, why not spend 5% more and get 4.56, 35s (that can be readily sold if you go 37s), stronger axles, tailgate reinforcement and and spare tire relocation (again helping with 37s) and the wider fenders to keep 35s or 37s road legal?

But, this relocation from mopar does fit a 37.Things not stock on the 392 is 4.56, tailgate reinforcement, spare relo, 1/2“ wider rim and small KO2 315s instead of 285s, mopar shocks. Everything else is stock.
My point is rims and tires are mostly taken off for something bigger/wider. Tailgate reinforcement and relo bracket is meh…. 35s fit on my carrier stock. I got the reinforcement as a separate option.
Agree, and would like to add that 4.56’s are overkill with 35’s. Comparable rpm to mph of 373 gears and 33’s is 410’s and 36’s, 456’s and 38’s or 39’s( forget witch) so If you are not going bigger than 35’s a re-gear to 410’s is cheaper. But if you want 37’s XR is a no brainer.Things not stock on the 392 is 4.56, tailgate reinforcement, spare relo, 1/2“ wider rim and small KO2 315s instead of 285s, mopar shocks.

I will admit, the 4.56 with 35s and the 8spd auto, even on the 3.6 moves like a freight train 0-60 considering its a jeep.Agree, and would like to add that 4.56’s are overkill with 35’s.

I would have bought an XR package for my 6sp JKUR in a second. No doubt, non 392 it is a no brainer for any jlur. Just think it is not a great value for a 392.I will admit, the 4.56 with 35s and the 8spd auto, even on the 3.6 moves like a freight train 0-60 considering its a jeep.
Everyone keeps saying that 37s on 8” rims are fine. Then why does every manufacturer not say that, not one…. I know they will mount them up. So is that it? Why have that spec at all then? next time you are with your off road buddies, see how many 37s are mounted on 8”s… aired down….17x8" rim (which is fine for a 37x12.5)
Probably the majority of them as thats a very common rim width. And fwiw they are 8.5" wide if using the actual beadlock rings... which if youre going to air it down regularly... I would.Everyone keeps say that 37s on 8” rims are fine. Then why does every manufacturer not say that, not one…. I know they will mount them up. So is that it?
