King Shocks 3.75 ID Coil Springs 8.5 x 500lb

King Shocks is well-known for their high-performance suspension components, especially for off-road applications. This 3.75-inch inner diameter coilover spring is designed to provide a 500-pound per inch spring rate over its 8.5-inch length.

This spring is intended for use with King Shocks coilovers, allowing you to tune your suspension's stiffness. A higher spring rate, like this 500 lb option, generally means a stiffer ride and can help manage body roll during aggressive driving or when carrying extra weight. The 3.75-inch inner diameter is a common size for many coilover shock bodies, and the 8.5-inch free length provides a good starting point for many setups.
