The FabWorx link suspension system uses a four-link with track bar. This design incorporates threaded 13⁄4x3⁄8-inch DOM tubular links. We ran massive EMF Heim joints at the axle end of the links, and bushings at the frame. These Canadia-made joints have a 11⁄4-inch shank and a high misalignment ball, which fits a 5⁄8-inch bolt. Made of billet 4140 chromoly, they are rated at 110,000-pound radial load and 44,000-pound axial load.
