About this part

Product Details

This product is a single Fox 14-inch long, 3-inch inner diameter coilover spring rated at 400 pounds per inch. It comes in a silver finish. This spring is designed to work with Fox shocks and is a common replacement or upgrade part for various suspension setups.

The 400 lb/in spring rate offers a firmer ride compared to stock springs, which can improve handling and reduce body roll during cornering and over rough terrain. The 3-inch inner diameter is a standard size for many popular aftermarket coilovers, making it a versatile option. Its 14-inch free length is also a common measurement, ensuring compatibility with many shock bodies.

When replacing coilover springs, it's important to ensure they are compatible with your specific shock absorber model. Always refer to your shock manufacturer's specifications to confirm fitment and recommended spring rates for your vehicle and driving style.
