The King Shocks 3.0-inch ID coil spring specified as 12 x 200lb provides a mid-range rate with a longer 12 length for suspension systems using a 3.0-inch inner diameter. It pairs with compatible shock bodies for replacement or custom assemblies and is intended where a 200lb rate over the listed length gives firmer support while maintaining usable ride characteristics.
