On the 73-87 C10's...which would be the better setup? I see KP is now offering a "Bolt-On" CantiLever setup for us. But ART also has had their Parallel 4-Link available for us for a while now. What are the pro's and con's of using each? About 99% of the trucks that are bagged around me, are all CantiLever in the back. (Either that, or Air-Over-Leaf) So, my guess is CantiLever lets you "hop" higher/easier?
