I'll get to the rendering in a bit...One of them at least...
I forgot to mention that we tried to keep every OEM part on the truck. We re-used the factory electronically controlled shocks which change the valving depending on road conditions. There were (and still are) 3 computers that control just the chassis on this vehicle.
The only good suspension we could fit in the back is a 3-link with a panhard bar setup because we wanted to keep the gas tank in the stock location. To keep cutting to a minimum (I really tried even though it's VERY cut), we actually designed the panhard bar to run around the upper 3-link bar. We chose to go with a panhard bar over a watts link as it provided us a better roll center since it is a top heavy SUV.
