Here is my path to 37s and my thoughts so far. will update as it progresses.

Basics:
2019 JLU Sport S
2.0 T
M220 Rear (anti spin)
30 front (I'm guessing)

Plan:
JLUR Springs (+1.5)
Rubi Shocks
Rear Sway links on front
RC 2.5 spacer lift (2.0rear and 2.5 front)
Mammoth Control Arms
RC front track bar
Terraflex rear Trac bar drop down
Regear to 4.88
Reprogram
37 BFG ATs
Black Rhino Wheels 9 (-12)

The Build:
This weekend I got the springs and spacers installed.


Thoughts:
So far Drives great.
Definitely lost some power (no 7th or 8th) but actually still has plenty of poop to get around.

Next Steps will be control arms and track bar
Last will be Regear and J-scan or tazer.

So far zero rub, should be fine for the limited wheeling i will do.

Nice looking setup. have a good time with building up. one recommendation is if you keep the dana 30 front make sure you get it trussed. or swap it for a rubicon take off setup. but for gearing you will be running on the thin side for 4.88's with that D30 front.. but that depends on the type of wheeling ( if any) you plan on doing. Cheers mate

Thanks!
Dirt roads and the lightest of wheeling is all this thing will likely see. In the event something breaks ill upgrade as necessary.

Maybe next time,
seems like overkill for the 1 or 2 times a year this thing will go into 4x. Of course if i get the bug maybe ill make the jump sooner, but house to the beach is the main journey for this jeep

Lifted just looks cool, and everyone knows you cant win if you don't look cool.

You think 456s are a better choice?
i expected much more power suck with the 37s and figured the 488s would be very necessary. As it is , if you didn't drive it stock you probably wouldn't realize its down on power.

I’ve had everything from the OEM sport 3.45 gears with 31” stock tires 3.45 gears with Rubicon 33’s then swapped to rubicon axle with 4.10 on 33’s bumped to 35’s on the 4.10 gears. Then 35’s on 4.88 gears. Then bumped to 37’s with the 4.88 gears. I like that combo alot for the 6speed but I also have the bigger Dana 44 axles front and rear. Now with the 8speed auto you could get away with 4.56 gears and 37’s it will still a little bit lung ish but nothing like 3.45 gears at 37’s

My build thought was make the jump now to 488 which I hear is great for 37s, and if i end up breaking things move to the rubi 44.

I thought this thing would be a total pig with 37s, and desperately need to go 488, BUT, I'm REALLY surprised how much juice this thing still has with 37s. (barked one yesterday).

Now that has got me thinking i dont need to go as deep as 488. I wonder if 456 will get me 7 and 8 back?

I am sure someone would chime in with the XR package on 4.56 gears and 37's but if your gonna spend the money and your ok with how its driving id just save and wait for a market place setup of axles. that will net you 4.10 gears.... a big jump from the factory 3.45's you will see a difference. I will say i really enjoy the 4.88 gears made The biggest difference when in 4L
