2019 Limited Air Ride Suspension OR1 or OR2

[runninram]

...good mornin', folks, is there any way 2 keep my truck in OR1 or OR2, thanx and Happy New Year!

 

[MrHankbot]

Yup, drive really slow. Or put in OR1 or 2 and then pull the fuse.

I don't recommend either, the first takes forever to get anywhere, and the second could potentially be dangerous.

Good luck.

 

[MrHankbot]

how so?

Because driving at higher speeds in OR1 or 2 will leave you with a higher center of gravity and a suspension that doesn't keep you as stable as it would in normal mode since it's sitting at the upper end of its travel under higher pressure. Think of it like lifting your truck and putting really hard springs in it. Does that sound like it will handle well?

 

[MrHankbot]

hardly "dangerous"

Until you make an emergency evasive maneuver on the interstate in OR2....

 

[MrHankbot]

Also, I didn't say it WOULD kill him, just that it potentially was dangerous. I don't think it's too much of a stretch to envision a situation where it might be dangerous to be sitting high on a really hard suspension.

The limitation of up travel and the removal of down travel in the suspension in the higher off road 1 and 2 modes is what makes it "dangerous" by affecting not just the stability (center of gravity) of the truck, but also HOW the truck handles in every situation. It's not about how tippy the truck is, but about the fact that with limited up travel, the truck can skip over washboard surfaces with quick undulations, or how with limited down travel, the wheels can and will come off the ground more often, causing minor dips to allow an airborne wheel to (obviously) provide zero traction in any maneuver, evasive or not. The same issue presents itself when the truck won't come out of entry/exit mode and people think its ok to drive around at highway speeds with .5" of suspension travel...
