triangulated 4 link if u have the space or the parallel 4 link is fine, much more articulation than the wishbone, the wishbone might have some sort of binding i think
either one will never bind on one of these dropped trucks. as long as you dont go two link you will be fine, and don't mount them in a reverse set-up. mount them all forward. the wish bone is by far the way to go, no side walking of the axle, the bags are easily mounted on the link for a better ride, looks better too. the main reason no one uses them is the factory fuel tank is in the way. we build custom fuel cells for that reason.
