We think you will agree that our new linkage is like nothing else available for the Speed King. Designed not only to far outlast the original but also designed to eliminate any play between foot board and beater. CNC machined from 1018 cold rolled steel and nickel plated to protect the finish our linkages are built with longevity and reliability. The rivet has been replaced with a grade 8 cap screw and nylock nut. No mods needed to install. Just remove the old rivet and replace with the screw. The bottom end is easily disconnected from the foot board for travel.
