King Shocks 3.75 ID Coil Springs 15 x 550lb

These are King Shocks 3.75 inch inner diameter coilover springs, measuring 15 inches long with a 550 pound per inch spring rate. They are designed to work with King Shocks coilovers and other suspension systems that use this specific spring size and mounting style.

King Shocks is known for making well-built suspension components, and these springs are no exception. They are made from strong steel and are built to handle the demands of off-road driving and performance applications. The 550 lb/in rate is a common choice for many trucks and SUVs, offering a good balance between ride comfort and control. This specific spring length and diameter are important for proper coilover function, ensuring the shock absorber operates within its intended travel range.

When choosing coilover springs, it's important to match the spring rate to your vehicle's weight and intended use. A spring rate that's too soft can lead to excessive body roll and bottoming out, while a rate that's too stiff can result in a harsh ride. These King Shocks springs are a solid option for those looking to fine-tune their suspension setup.
