I found some info on the Jeep site for the JKU Rubi...

Quote:
Wrangler Unlimited offers added Jeep vehicle capability with 10.5 inches of ground clearance (Rubicon), a 44.4-degree approach angle, a 40.5-degree departure angle and a 20.8-degree breakover angle.

Rubicon has Best-in-Class ground clearance+ along with Best-in-Class approach and departure angles+. The front air dam is removable to provide added flexibility (better approach angle) when off-roading.
I think they also discuss it in one of their videos.

And then there's this.

Is the brakeover point the roll point

Smittybuilt has a free app for the iPhone that shows a red zone of anything above 45 degrees.

There is no magic number, every situation, every rig, every driver plays a part. Best way to figure out your tipping point is to go flop it over on the trail.....after you climb out of the window stand back and say " that was to steep" or take it down the street and make a sharp turn, when it rolls, again climb out your window, stand back and say "that was to fast"

The tipping point both lateral (roll over) and longitudinal can be calculated but it highly depends on two variables that are different in every case:
1. The location of the CG
2. The amount of traction (tires and surface conditions)

IMO, this is not a number that a manufacturer would publish.

If you are going to push the envelope you can use a phone but I would use an attitude meter for simplicity and reliability, and keep the angle reasonable. IMO, the angle always feels larger being in the Jeep than it really is particularly in taller Jeeps.

Sorry about that. I probably did pay the .99 for the app. I have a lot of fun with it both in the Jeep and on planes.

Did you ever just want to see what would happen if it hit 46 degrees? I am sure there is someone out there who has...just because the gene pool is amazingly shallow in places. Brought to you by the society that must warn you "WARNING: COFFEE MAY BE HOT" on your cup.

It will tip over faster than cars and lower SUVs in general. I suspect the 2-door will do so quicker. Don't blast around like you would in a normal lower vehicle.

EDIT- An excerpt from some research:


SAFETY
Safety is not the Wrangler’s strong suit, either. While most vehicles have six to ten airbags, the Wrangler comes with just two front airbags as standard. Front-seat-mounted side airbags are optional ($495) and side curtain airbags, which provide protection in a rollover, are not even offered; instead, the Wrangler has an exceptionally stout roll bar that cages the passenger compartment. There’s a reason for the lack airbags: Jeep enthusiasts use their Wranglers for hard-core low-speed rock-climbing, where a gentle roll-over is almost a non-event. Without an airbag deployment, they can simply push the Wrangler back onto its wheels and try again. But if you’re driving on-road, you’ll want the extra protection that side airbags provide.

The Federal Government has not crash-tested the 2013 Jeep Wrangler, though they gave it only 3 out of 5 stars for rollover potential — no surprise given its narrow stance, short wheelbase (distance between the front and back wheels) and big, bouncy off-road suspension. The Insurance Institute for Highway Safety gave the Wrangler a best-possible “Good” rating for front crashes, but side impacts without the optional side airbags were “Poor” (the worst rating) for the 2-door and “Marginal” (second-worst) for the 4-door.

Isn't that why beer comes in long neck bottles; to increase the spillover angle.

So are you implying that people who enjoy pushing there rigs to the limits are idiots that should not reproduce?

Or are people who stop when some phone app (made by Smittybuilt of all people)tells them too just sheep?

If you are actually doing something that could possibly make you flop you should be paying 100% to your rig, not looking at your phone or some gage glued to your dash.

Besides most flops that I have seen are from the COG suddenly shifting. They dont make an app for that.

Neither of the above. I was referring to the type who would see "Hmmm it is red after 45 let's see what happens if I try to push it to 47" and who have not a clue what they are doing.

OOH! Hadn't thought of that! Will try that on my next group trail ride. I know the other's will appreciate my dolling out instructions. I mean, who doesn't love being told what to do. LOL

Yep, best you take notes, because I give pop quizzes at the conclusion of the trail run.

But in all seriousness, I would like to have an old beater to take out and show people what not to do. Would actually be fun.
