The King Shocks 4.5-inch race shock, 18 inches long, pairs five-tube bypass valving with a piggyback reservoir for a compact external fluid solution. Built on a 1.25-inch shaft and fitted with large 1.00-inch bypass tubes, it routes hydraulic flow through multiple bypass passages to produce staged damping. The piggyback design keeps reservoir volume close to the shock while providing multi-tube bypass control.
