Because 4 link's bind when one end of the axle moves up and the other end moves down. They impart twising forces on the axle turning it into something similar to a swaybar. Triangulated 4 links can cause a lot of bind if they're not set up well due to the bars themselves twisting.thepunkerguy said:Awesome man, i have always liked the watts link better than a panhard bar. I have always had one question though. Wouldnt just having a triangulated link setup prevent even needing a watts link or panhard bar? So why would someone get a paralell link setup and have to pay an extra $500 for a watts link when they could have just got a triangulated link to start and avoided any of it?
