King Shocks 3.0 ID Coil Springs 16 x 400lb

These King Shocks coil springs measure 16 inches long and have a spring rate of 400 pounds per inch. They are designed for 3.0 inch internal diameter coilovers, a common size for many performance suspension setups. The spring rate is a key factor in how your vehicle handles; a 400 lb/in rate offers a firm but compliant ride, suitable for vehicles that see a mix of on-road and off-road use where a balance of comfort and control is desired.

King Shocks uses high-strength steel for their springs, ensuring they can withstand the constant compression and extension cycles they endure. This well-built construction helps maintain the intended spring rate over time, providing consistent performance. The 3.0 inch internal diameter is a standard measurement, making these springs compatible with a wide range of aftermarket coilovers that utilize this size.
