wow...i was told that the 3 link is actually better for articulation.....i had a simple suicidedoors.com 3 link on my bagged dakota, but it only would lower it so far.....so this past spring i switched my back half over to a 4 link setup, it lifts higher and drops lower...the only thing that ive noticed about the 2 were that with my 3 link on the |removethispart|@$$, i could make the truck sit sideways....now it doesnt have the killer side to side motion with the 4 link.....also ive been told that the 4 link can handle more h.p.....not an issue with a zuki....btw....i work |removethispart|@ skinny kidz customs part time as the chassis engineer, and im certified thru airlift to install their products...ive had my mini truck bagged for almost 10 yrs..masters degree from university of michgan in mechanical engineering, so i kinda know a little about this subject
