The King Shocks 4.5-inch race shock, 16 inches long, pairs five-tube bypass valving with a piggyback reservoir for compact external fluid capacity. Built around a 1.25-inch shaft and large 1.00-inch bypass tubes, it routes fluid through multiple bypass passages to support staged damping behavior. The piggyback layout keeps reservoir volume close to the shock body while providing multi-tube bypass control.
