Even at stock ride height, since there is no end link, under suspension extension the sway bar is pulled in and on suspension compression it is pulled out. When a double end link is used, it will allow for angle change in the link intself versus pulling on the dogleg of the swaybar. And as for intended purpose, these are off road rigs, they are designed to take advantage of the entire suspension travel. When we raise the torsion bars we're mearly just raising normal ride height farther up on the travel parameters. The sway bar should be designed to function properly from fully extended to fully compressed suspension travel. Same as for the CV joints. They are designed, hopefully, to withstand any angle between the given stops of suspension travel, with correctly adjusted camber, that is important. Anyway, these are just my theories, and we all know that theories are nothing more than opinions, and we all know what they say about opinions.......
