The King Shocks 2.5-inch ID coil spring with 10-inch free height and a 350 lb/in rate is intended for coilover assemblies that accept 2.5-inch inner-diameter springs and require very firm support. It offers increased travel and a high spring rate for heavy-load or performance-focused setups. Use these springs to significantly stiffen suspension response and manage body motion while maintaining compatibility with King shock components.
