<strong>07. </strong>The front package was effective, robust and, without question, much more prepared for a life with OFF-ROAD than the stock suspension would have been. But the four-link conversion did create one possibly negative (possibly positive) effect: Four-links move more freely (less binding during articulation) than radius arm suspensions do. When we converted the truck to a four-link (from radius arm), our Super Duty’s front suspension allowed the truck to lean over more easily. The suspension articulated better in uneven terrain, but it created a little more body roll on pavement.
