Now that my Jeep is on 40s I will throw in some more numbers.
It is a garage ornament for now until I finish the CJ-10.
40 inch competition Maxxis Creepy Crawlers on 17x9 Trailready double beadlocks.
74" to the top of the cage, 22" to the bottom of the skid.
I took this thing all over Moab on 35s and did not have a single problem ever with breakover angles, COG or articulation. It sits low, the center of mass is low, and the skid is pretty high in relation, flat against the frame.
Leaf spring rigs are a different beast than link suspensions, and need a different driving style. They do not articulate well, no matter what your ramp measurements say. They spend a lot of time carrying tires over things, lockers are an absolute for a leaf sprung rig driven hard.
My rig is light for a leaf sprung truck, last weight was 3800 with driver before the skid plates, probably now weighs just under 4000 without driver.
Watch the tires on Golden Crack. I forgot to engage the front axle and drove across in 2wd, which is a testament to how well this rig drives, but tires to not drop and the whole rig just kind of floats across. Much different than a link suspension, where the tire would have dropped in the crack and then crawled back out.

If my rig had a higher center of gravity, that tipping action would have certifiably sucked. As it was, it was just another little obstacle. Not a big deal at all.
It look like it has a high center of gravity, but all the heavy stuff is mounted low in the chassis.
It has a 101 inch wheel base and a flat skid. It loved the shelves and dropoffs in Moab. I stopped here for a photo, I just let the clutch out and it popped right up. No drama, no hitting the skid, and even if I did, there would be no damage, it is all a flat piece of 1/4 inch steel.
BUT, this is just about all it articulates. Just about any linked rig would be at about half travel here, but I was barely touching the ground on either side. I went everywhere the linked guys did, just with some more dramatic carrying of the suspension and many more 3 wheeled moments:flipoff2:
I guess my experience, summed up, is:
Lower it as much as you can
Raise the drivetrain just as much as you need to to make a flat skid
Mount everything heavy as low as you can
Enjoy the look of fear on your linked buddies face as you go everywhere they do... on three wheels!
