The King Shocks 2.5-inch inner-diameter coil spring is a replacement coil spring for coilover suspension assemblies, defined by its explicit size and rate. This version is specified as 12 x 400 lb to offer very firm support for heavy-duty or performance-oriented setups. Match it with compatible 2.5 ID shock assemblies and adjust valving to control body motion.
