I've been rocking this setup for several months now and couldn't be happier. The torque from the 2.0T handles the 37s without breaking a sweat. Why no lift? Simple; I wanted to keep suspension geometry as close to factory as possible while still being able to swallow 37s. You NEED 37s, even 35s look puny on JLs IMO. I'm not rock crawling so 100% clearance at MAX articulation was not the focus. If I'm able to wheel mild and moderate trails without issues I'm good. This setup does exactly that. The icing on the cake is that "low and wide" stance you get with no lift. Its all personal preference guys! Its all about proper wheel offset/backspacing + tire selection for clearance. The point is you can run 37s (not just any 37 setup though) on a stock JLUR without too much fuss.

You must rub the back of the rear tire in the well like 200 times a day. I have a 3.5” lift and would hit that thing daily driving before I went to aftermarket wheel well liners.

Glad what you have works for you. Wouldn’t work for my needs.
I agree. I'm on 37x13.5's with plenty of offset (no inner well rubbing) and I lightly rub the outer lip of my rear fender flare at max articulation - even though I'm running the bumpstops that should prevent that. I can't imagine running 37's with no lift, as I'd be chewing up the fenders like mad without an enormous bumpstop!

I would bet nearly half of all rubi's sold will never do any "hard off-roading". They were bought for other good reasons like getting around in winter snowy roads or just because they look awesome and require very little mods compared to a sport. whatever the reason is don't matter, the only thing that matters is we all enjoy jeeps....for our own reasons. JMO. Getting back to the subject, I think those 37's look great on your Rubi with no lift makumozosd.
My Rubicon is the last vehicle I'd want to be driving in serious wintry conditions, my wife's Civic is at the top of the list.

Stopping is your friend.
Stopping is important. I also think it's important for some people to be able to get through 2' drifts of snow down unmaintained County roads. So yeah, different strokes.

Looking great!
How do you like the spare delete kit? I just bought it and going to install this week.

I like it a lot - it was my very first mod. Cavfab makes the slickest delete kit in the market. The only thing missing was the plugs to cover the tailgate holes that remain - I found some on Amazon for cheap. You will get a free 1/2" lift in the rear give or take and its nice to actually see out of your rear window! I know its not for everyone but I personally love the boxy look of the Jeep without the spare.

This is why I'm looking into synergy spacers... and the OP's tires.. are those 37x13.5?
Nope, K02s in 37" only come in 12.5. A 13.5 width would definitely causing more clearance issues with no lift.

You are crazy not extending your bump stop. Suspension height is irrelevant here. Bump stop is determined by tire size. If you flex your suspension it will rub (in many places) you should at a minimum address that.
Any idea what size bump stop would be needed for this? My logic tells me that if a 35 fits, a 37 should only need a 1" longer bump stop (due to the 1" larger radius).

Sure, but it came set up for 33’s, not 35’s.

The only way to get it right is flex it and see what it needs.

I’d guess 3” would be safe. May be able to get away with 2”. Typically you buy a kit and it comes with enough to do like 4” In 1” increments and you just use what you need.

So I can’t run 35’s bone stock at full articulation on stock wheels if I add a Rubicon to the stables? Let’s assume @ gvwr.
I have ran mine on two medium trails with 0 rubbing with swaybar disconnected

I remember watching a vid on youtube where someone with a Rubicon took off the springs and ran it slowly on the bumpstops and had no rubbing ...

I can confirm mine rubbed with 315 BFG KO2's. I was running tough trails when I experienced rubbing.
