LCoG and long arm lifts

Trying to keep things simple with a probable reason some are so concerned with their COG.

Many years ago Jeeps had a reputation being somewhat easy to roll/tip. That however was with the old CJ and older models, which is why Jeep developed the Wrangler YJ. Jeep was being bled by numerous lawsuits relating to the tendency to roll so they had to fix it... hence the Wrangler YJ that came along in 1987.

The easy to roll complaints are still hard to quiet among those who know no better so the reputation still exists among some, though in fact it's no longer true.

Even this TJ, built by mrblaine with a suspension lift and bigger tires, had no problem with rolling as shown here. The camera for this photo was being held level so the amount this TJ is tipped to one side is not exaggerated. Nope, it did not roll.

The below is the above Jeep with a few minor changes.

Low-COG builds for Wranglers are simply not needed. Though I guess It would be possible for a clueless type to build his Wrangler to easily tip if he fucked up and screwed up every possible thing that make it easier to roll but it would be a terrible build by a clueless dumbass indeed that might raise the odds of a roll/tip.

The tires completely out of the body. That is not a good picture to show tipping point for a stock length axle. I'm guessing at least 70" axles or more.

Why you gotta be that way knowing full well that 99% of the time I'm gonna come right behind you and slap the dogshit out of your response?
You don't like that one, fine, how about this one with 35's, 4" of backspacing on Alcoa rims, stock width fucking axles and the rig is in motion?

Stop guessing, front is 65 and rear is 64 on Walker Evans bead locks with 4" of back spacing and 37's.

That looks like fun
 
Years ago when they came out with the double decker buses in England everyone said they were going to tip over, and the engineers showed on some sort of contraption just how far over one of those busses could lean without tipping over. Anyone ever done a similar test in real life with a TJ?

We have, many times. There is a steep walled sand wash in JV at the bridge. We've tied a tow strap to the roll bars on two rigs and used one to catch the one on the slope if needed so you could drive on the slope parallel. What we learned was you will be very uncomfortable trying to stay in the seat long before it tries to tip over. It is much farther than you would think.

Your pic you posted reminded me of the bus picture. I've never measured how far over I could tilt on purpose, but I have been in some really sketchy situations. I did have a passenger bail out on me once I was over so far, he just unbuckled his seatbelt and stepped out and walked away. I've actually had more scares almost going over backwards.

The fear of leaning over is why we have the LCG bullshit in a misguided attempt to not be so scared when the rig tilts. I know some very smart folks who have raced KOH that ran some way fucked up backspacing on stock width axles to not be as scared when it gets tippy. 3.25" backspaced rims on 1 1/4" spacers which delivered an effective 2" back spacing. Great for testing ball joints though. 4-5 trails would eat up any of them.

This does not look like a half assed rig. Why so much track width? I just measured mine and would need 70" axles to get the tire to the edge of the tub with 3.75" bs.

My wife commonly says, “let me out.” This time she forgot. It was not scary to me.

With my passenger tires in the ditch in the pic below the mirror was dragging the ground, the frame rail was in mud, and the driver front tire was a good three feet in the air. I was uncomfortable, backed up twice, it was a no go, so went forward, turned into the bank and the tire started coming down as I drove out. I’m sure it was fine. Wish I had pics of that one, but I had come to the ORV alone and the guys I asked to help me out if I got in trouble were a hundred yards back. IH8MUD.

The phrase "half assed" and that specific Jeep do not even belong in the same universe. The attention to detail and the execution is at a level that is hard to describe with words. This jeep, and Garza's Jeep (I think I shared the link with you before) that Blaine did are the very best I've seen anywhere, period.

Will you stop already, please? I don't know what your obsession is with shit that confuses you, but it is obvious that is not very hard to do. Those are 14" coil-overs set up around 50/50. Look how much shaft is showing on the left front shock. Look where the top of the right front tire is.

Do you keep at it like that, repeatedly pushing back, just to piss people off? Blaine built that rig from scratch, I saw it while it was being built many years ago. He already told you the axle lengths are not 70". Once again, per Blaine.... "Front is 65 and rear is 64 on Walker Evans bead locks with 4" of back spacing and 37's".

I wish I had a photo but I pissed my wife off one time going up a 150 yard climb where the right side was so eroded it had turned into a V notch but was too steep on the right to get tires up on so there was no choice but to go up with the passenger tires in the bottom. I was probably 2/3 of the way up and she was seeing her mirror get closer and closer to Earth when she finally freaked and told me to back out of it. I told her no effing way was backing all the way down that safer or more expedient than seeing it through. 🤣

I told her I'd already driven up it two weeks before with our 4 year old (now 7) in the Jeep so I knew what I was getting us into and I knew we'd have no problem. It's uncertain whether that information helped or hurt.
 
Please, then insult. I

The static tipping point is one thing, but what it doesn't tell you is how much safety margin you need to reserve for things like hitting a rock on the high side that might bounce you past the point of no return.

My wife freaked out regularly when in my TJ even when nothing all that difficult was happening. I think just needing to be in 4x4 was enough to scare her. Once she jumped out when she saw a 10-12' tall rock ledge/climb coming up. I was in the lead so she couldn't see others doing it to see it wasn't all that difficult. She refused to get back in and crawled up the side of the ledge to get to the top, skinning her knees and arms several times to the point of a bit of blood oozing out. She was hating me about the time I went up and over the climb without problem as she watched from the top lol.
