Roll Over Angle

MIGeezer

I've been doing some homework and can't find any info. from Ford about what the roll over angle is, (ROA). I have seen some info that says 35-40 degrees side and in the 45-50 degrees front/back. I realize these are numbers and there is all kinds of physics that change these numbers. I guess that's why Mr. Lake told me I would need to know this stuff some day, when I got a C- in physics.

So, is it safe to say for side if you are in the 30-35 degrees you should start to be concerned, and 35-40 for front/back? I hope I never have to worry about this, but it is good info to have.

Thanks.

There are a few things to look at. The degree with which the the vehicle can pitch up an incline or down a decline. There’s the roll which is the degree a vehicle can roll side to side without rolling over. Then there are the approach, departure and breakover angles, which tells you how steep of an incline you can approach, how steep of a decline you can depart from, and the breakover is the angle between the wheels front to back. The approach, departure and breakover angles are easy to look up online. The pitch and roll aren’t. Those come from experience. I did a 31° pitch up an incline this weekend in my Bronco Raptor in Moab and it was pucker time. My pitch down I got up to 28° and side roll about 21°. I’m curious what the limits are as well if anyone finds any documentation.

I’ve done 24 degrees side to side and 42 degrees up and down. That pucker factor is wild. Any “official” numbers would be in a controlled environment with a Bronco set up in a specific configuration. No way they would report those numbers and then make people believe they could reproduce that on something as random as a constantly changing trail/terrain.

Nice pic., but the key word is PUCKER. The older I get the lower it gets. Thanks for the info.

After hiting a deep gully can confirm that a roll of 30⁰ will not topple a stock badlands sas. However, would recommend having a passenger as a counter weight and a new pair of trousers for after you make it through.

Pix or it didn't happen! 😂

I was told at the Bronco Off-Roadeo that Ford had tested side angle to 40 degrees. That seemed insane to me until I realized I did this:

Feel free to watch the whole thing, but that's just before the really crazy part starts. 😂 My friend at the end comments on what he saw from his vantage point.

Prior to that, I had done about 29 degrees incline and my son and I each had done 29 degrees lateral on different occasions. That is when everything that isn't held down moves to the low side! 😄

I feel like I was really up there! Really...really?? :0)

I'm not sure if Retnuh D meant a 30-degree pitch or 30-degree roll, but this is my son at 26 degrees, and this was about as far as we dared try with a non-disposable vehicle. 😆 I can see where there might be a couple of degrees left, but explaining to my wife why the side of the Bronco is all crunchy was not part of the plan. 💀

I meant 30⁰ roll. My passenger leaned out the window to keep us from toppling. I went on the same trail a week prior and only hit 23⁰ so I figured it'd be fine in the dark. When I hit the same gully in the instance mentioned the wheels slid down and it got a little spicy.

Love the pic on fins and things, came down that recently in my stock black diamond with 32" tires and no lift, definitely the most terrifying thing I've done so far lol 🤣 yours looks amazing going up it
