The King Shocks 2.5-inch ID coil spring shown as 16 x 450lb is a dedicated suspension spring for custom shock and spring systems. The 2.5-inch inner diameter ensures compatibility with matching shock hardware, and the 450lb specification gives a higher-rate option for increased load control. It’s suitable for rebuilds or bespoke setups requiring that spring rate.
