The Dumpster's front suspension will have three leading arm links and a Panhard (track) bar to locate the axle. Each link is 40 inches long and made of 2x1/4-inch-wall tubing. The 4140 steel links ends are from Evolution Machine and have massive 1 1/4-inch-diameter shanks. These greasable, rebuildable Heim joints have a 1 3/4-inch-diameter ball with a 3/4-inch bolt hole and an overall length of 6-plus inches. Evolution also supplied the jam nuts and the threaded bungs that will be TIG-welded into the link tubes.
