The King Shocks 4.0 Series Race shock is a piggyback reservoir coilover-style damper designed for demanding use. It features a 1.25 in. shaft, piggyback reservoir and 1 in. bypass tubes to manage fluid flow and heat during heavy duty cycles. The 4.0 Series construction targets rigorous shock applications where a separate reservoir and bypass valving are preferred for consistent damping and improved thermal capacity.
