Thanks Dennis, I'd say the roll came from excessive speed over rough terrain, ending up with the truck bouncing and finally rolling on its roof. I learned my lesson, "slow as possible, fast as necessary".
The Calmini UCAs really just lower the Ball joint from the where the oems are, Id say you could do the same thing with the oem UCA, flipping the balljoint to the bottom, and adding a .5" spacer to it. It does require substantial amount of shims to get it aligned, even when the T-bars are cranked for ride height. Also If you do get them, you must modify them before install to accept a grease fitting, the poly bushings require grease to not stick and wallow out. Also the use of petro grease deteriorates them, I use pure silicone grease. I swapped bushings and started using the "super grease" brand silicone, stopped the squeaking I was getting. They also send a lot more vibes into the truck, they don't absorb shock as well as the oem rubber bushings.
As for lifting a wheel, it takes a lot to lift a wheel actually. I have done it on occasion, but its when I'm driving over a large "ditch". The poly bushings I thing are more responsive (they allow better movement) than the oem control arms, on the front and back. The wheel falls into dips easily, Also the fact that I don't run and "sway bars". I usually have all my wheels on the ground all the time, the lockers help it push itself up also.
My next adventure into this rig is install a set of Revo, 3:1 gears in the TC, and maybe trying another rear locker. And maybe some bigger tires, or just Mud terrains. I've yet to find a place I couldn't get that I actually wanted too.
