Product Description

The King Shocks SPR3-14-300 is a 3.0" inside diameter, 14-inch free length, single-rate coilover spring rated at 300 lbs/in. It is designed for use with 2.5" diameter coilover shock bodies and is compatible with King Shocks coilovers as well as any other brand requiring a 3.0" ID spring. As a linear single-rate spring, it compresses at a constant 300 lbs per inch of travel, delivering predictable and consistent handling response throughout the suspension stroke - making it a reliable choice for coilover builds where a linear force curve is desired.

Manufactured in the USA from high-tensile chrome silicon wire and wound specifically for off-road applications, this spring has been developed and validated through extensive real-world testing and King's racing programs across Baja and Dakar. Closed and ground ends ensure the spring seats flat under load for accurate deflection. The spring rate is etched into the top coil for easy identification in the field. King backs this spring with a Lifetime Limited Warranty against sagging and breakage to the original purchaser.
