Side hill angle

[wanderer]

What side hill angle is a jlur with the recon x (35” tires and a small lift) able to handle ? How much angle have you seen on your gauges?
in my younger days while learning I tried to back down a steep slope in my cj 7 (77 golden eagle soft top) and it got away from me. Stopped on a side hill angle of 2:1 26 degrees. I measured it with my brunt on compass ( geologist tool with an inclinometer) in it scared me so …… bad. But not sure about todays. Jeeps ? Is there a warning that comes up
On the roll gauge on the off road pages ? Let’s hear your stories how you learned what angle side hill you can traverse.

I'm running 35s with a 2.5" lift. I hate sidehills. Anything above 17-18 is too much for my butt. That said I've seen 28 a time or two and gotten as far as 32 momentarily. Measured by the onboard inclinometer. No pics, just enough time to glance while in full panic flight mode.

Well I run out to 53 degrees. BUT not in OEM this is after a making mods that contribute to lower my CoG.

Here it is in action:

34 is the worst (best?) I've done. That's the only time I've been scared in my Jeep. Yeah, I should have had a spotter. No pics since I was too scared to try to get out. I was much more concerned about it rolling.

That's with 37s, 3" AEV lift, heavy RSE sliders, and a roof rack with a massive awning. Well over 6k pounds and definitely not optimized for this type of thing.

NVM skids, but they're incredibly light aluminum so they don't significantly lower my center of gravity.

You want a number. I'll get to that.... But first, keep in mind the gauge is a lagging indicator. It takes critical time to detect the angle, calculate, digitize the image, and get it onto the display. Not a lot of time, but then, rollovers happen fast. All it takes is for a downhill wheel to drop into a hole, or an uphill wheel to climb a rock, to turn a "steep but OK" slope into a flop.

So don't put too much faith in the gauge. Also, in a sketch situation, your eyes need to be on the trail, not on the instrument panel or front camera display.

I pack my Jeep, and my Tacoma before that, with weight low. No roof rack, no high up stuff attached to the tailgate, no rooftop tent, etc... So, the number: My experience is that a well packed rig on a moderate lift with moderate size tires (e.g. 3.5" lift, 37" tires on a JLU) is reasonably stable on a 30 degree side-hill.

If stopped on a steep climb and unable to continue, the best practice is to back down, rather than get crossways attempting to turn around.

Don't "over steer" a descent. The best general path is straight down the fall line. The further you turn away from that, the more likely to get a perilous roll angle.

If starting to flop, turn down hill. It may be necessary to apply a little acceleration. Braking can actually send the rig over. Past a certain point, gravity will have its way, and the rig *IS* going down that hill. But, the adept driver may be able to keep it on its wheels, rather than tumbling on its side.

OldJeeper is modest.

There may in fact be relevant modifications to the Jeep. But that maneuver was only accomplished after thousands of hours of time-in-the-seat.

The most important modification is to the stuff between the drivers ears.

I'm not drivin' that line.

Thank you and YES, TnT (Time in Trail) is critical to success on the trail.

When I had my shop and some guy want a lift I would always ask. Is the lift for the street (Sonic drive in) or trails?

If street then go for it and if for trails, before you add a lift, better get a set of GOOD TIRES because they will make the biggest improvement to begin with. Then run some trails and we can do a lift later.

In the world of Jeep, from TJ on, the Jeep will outperform the newbie driver every time, you got to work you way up to need a lift or anything else.

No warning from off road pages because everyones setup is a little bit different i.e. 1 person or 2. My max roll angle was 21° to the passenger side. A 3 oh sh*t moment for me.
