The King Shocks 4.5-inch race shock in a 20-inch length features five-tube bypass valving with a piggyback reservoir for compact external fluid storage. Constructed with a 1.25-inch shaft and large 1.00-inch bypass tubes, it routes hydraulic flow across multiple bypass passages to deliver staged bypass damping. This five-tube piggyback arrangement offers reservoir volume close to the shock while maintaining multi-tube bypass control.
