The King Shocks 2.5-inch ID coil spring, 10-inch free height with a 400 lb/in rate, provides a very stiff tall-spring option for coilover systems that accept 2.5-inch inner-diameter springs. It’s aimed at installations needing high compressive resistance and increased travel. Install these springs to achieve firm suspension control under heavy loads or aggressive driving, allowing targeted tuning of handling characteristics while retaining existing shock hardware.
