The King Shocks 3.0 ID coil spring is offered with a 3.0-inch inner diameter, a 12-inch free length and a 500 lb spring rate. Suited to coilover-style shock bodies that accept a 3.0-inch ID spring, this heavier-rate option helps increase load capacity and firmness. Choose it when your suspension setup calls for a 12-inch spring with a 500 lb rate to achieve the desired handling balance.
