Picking the Right Coil Springs
JKS J-Rated Suspension Systems feature custom wound, progressive rate coil springs. That means the spring rate increases as the spring is compressed. You and your Jeep enjoy a plush ride during low load driving scenarios such as highway cruising with increased performance as each spring compresses. If you carry a significant amount of extra gear in your Jeep, some J-Rated suspension systems are available with optional high-rate coil springs to support the additional weight.
