The King Shocks 2.5-inch ID coil spring specified as 16 x 350lb is a suspension spring intended to give a defined spring rate for custom shock and spring assemblies. With a 2.5-inch inner diameter it works with matching shock bodies, letting installers tune load support and ride height. Use it in rebuilds or custom setups where a 350lb rate is required.
