Roll Over Angle

OrangecrushBronco

I don't remember how far they had us go at the Nevada Off-Rodeo but I do remember thinking if it weren't someone else's rig that I opted for the insurance on I would likely not trust doing it. It sure felt like I could have reached out the side and touch the ground, I wouldn't though, seems like a quick way to lose an arm.

I take my Honda Talon R out on some of the more severe trails here in AZ. They come factory equipped with full door nets - for a reason. Natural instinct is to reach and brace - not a good plan. Ask me how I know 🤣

Well I would probably get out with your wife. I have a hill I mow at my house. I've been told a zero turn won't hold it. I put the Bronco on it. It's about 15 degrees according to the Bronco. It was enough for me. That's why I started the post.

At BORT they got us to 16 degrees on the test track and everyone in the Bronco were very concerned. Now 20 degrees seems easy and 26 degrees front to back is piece of cake.

Been at 28% and it is a pucker. For sure.

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.

That pic looks like the Bronco stopped to take a leak on the tree.

If you notice, the picture was taken from the perspective of the Jeep that was following me. Bronco was marking the trail to assert dominance.

At BOR Texas, they said front/back was 37 degrees max. But it was something about oil/fluids leakage and not roll over.

No mention on side to side.

Most folks get good and uncomfortable at 20 degrees to the side. 35? Hmm.

I've been up to as much as 18 degrees, and well, I was gettin' a bit uncomfortable, but I am working on being comfortable with being uncomfortable. 😁

I managed to reach 20 degrees in both pitch & roll this past Sunday going down a trail. It was......exciting. Then had to go up the same to get back. I'm sure cargo weight & placement will change the outer limits.

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.

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 did 33 degrees incline in a 2dr., and you can maybe do 1 or 2 more max, at which point you will topple. Strapping down the front will give you a bit more, but we are talking stock here.
I know the 4dr will allow you a couple of degrees steeper, and I read somewhere that the 4dr will go as far as 37 degrees. The gentleman that claims to have done 42 incline, I am inclined (pun intended) to disbelieve that.

I'm just glad I have the front Camera. The most hairy for my was a steep incline cresting at a hill with no visibility down below until I remembered my camera. I knew there were other Broncos and dirt bikes in the area and was worried about running into someone, without enough room on the side to spot.

At the Moab OffRodeo I saw 27 degrees lateral . I reported 24 to the guide when he asked but after moving a few more feet it reached 27. I should have taken a quick pic of the dash. Everything seemed well within the Broncos limits so there was no pucker factor at all. When the guide asked how it felt I just said I am used to riding sportbikes on road courses, so I just had to fight the urge to put my knee down. If the doors had been off maybe I would have :)

Kenny Roberts style.

As a kid growing up in the 70's I loved Kenny's riding style. He's the reason I got into bikes and the Yamahas specifically .

On one of the early (pre-off roadeo) driving events that Ford held, the pro-driver during the instruction session basically said anything past 30 is a tip over risk side to side. This was when we proceeded to an obstacle that took us to 28-29* of side to side incline. I took both my brothers to this event and they were sitting in the back seat - as I made the left turn off the swaybar disco obstacle, we were at 29* and one who was on the drivers side was literally resting on the door and not his seat anymore and squealing - ok that's far enough. My other brother was giddy like me (we are the gearheads of the family - lol) If only I had video of that 😂

There are soooo many factors that go into this, that you cannot go off degrees alone. Those are Ford's numbers in a test vacuum with all baseline controlled factors. The minute you put passengers and cargo and equipment in your Bronco, this all changes. Do you have a roof-top tent, do you have 2, 150 pound passengers, or 4, 250 pound passengers. Are heavier passengers both on one side of the vehicle? Whats your tire pressure, do you have a roof rack, etc etc. These are all factors that dramatically change the point in which the Bronco could roll. Speed and driving surface also play into this. So one bronco may roll at 30 degrees while another may not. Just food for thought but I wouldnt base your calculations on what the gauge in the dash is telling you compared to the stated numbers bc the Ford published numbers are simply just a reference for testing and specifications sake.

Careful now. Are you implying fat people cause roll overs ? lol

At the Bronco Raptor Off Rodeo they suggested 26 degrees on the side is a good max. Anything after that you are moving perhaps into risky territory. Also, of course we need to take into account the surface we are on. This number may be specific to the Raptor. Like said above once you hit 30 degrees.......
