I have more pics to throw in there, maybe today. The rear triangulates upper and lower (a little). The exhaust is a pain to work around the frame side of the uppers but having them on the outside of the frame makes it pretty sensitive to roll center height and the double triangulated system works well pretty much no matter what. and gives a LOT of real estate to mount the coil over shock or even a straight coil spring if you want. And since the lowers attach to the frame rails it's way easier to build. If they have to converge to the center of the truck you have to have a super beefy crossmember that is tough to build in. Attaching to the frame is a natural easy to deal with strong point.
