Early Ford Broncos were the first 4x4s to use a coil-spring radius arm suspension. This is a true three-link setup with the two radius arms and a track bar. This design led the way to many more unique suspension designs. Note how the shock is mounted perpendicular to the straight line of the vehicle - this better maintains damping effectiveness than shocks mounted at an angle.
