The King Shocks 3.0 ID coil spring has a 3.0-inch inner diameter, a 14-inch free length and a 450 lb spring rate. Intended for coilover-style use where a 3.0-inch ID is required, it supplies a substantially firmer rate combined with longer free length for adjustment. Use this option when a 14-inch, 450 lb spring is needed to achieve increased stiffness and load capacity.
