What does the spring rate (350 lbs/in) mean for my vehicle?

A 350 lbs/in spring rate means that for every inch the spring is compressed, it will exert 350 pounds of force. This rate is stiffer than most stock springs, which can improve handling and reduce body roll during cornering or aggressive driving.

What are the key dimensions of this coilover spring?

This Fox coilover spring has a length of 16 inches and an inside diameter of 3 inches. These dimensions are critical for ensuring it fits correctly onto your coilover shock absorber body.

Does this spring come with any hardware?

This product is for the coilover spring only. Any necessary hardware, such as spring perches or collars, would typically be part of your existing coilover assembly or sold separately.

About this part

Product Details

Fox is known for making high-performance suspension components, and this coilover spring is a solid option for anyone building or rebuilding a custom suspension system. This particular spring measures 16 inches long with a 3-inch inside diameter and a spring rate of 350 pounds per inch. It's designed to work with many popular coilover shock bodies that accept these dimensions.

The 350 lb/in spring rate offers a noticeable increase in stiffness over stock springs, which can lead to improved handling and reduced body roll, especially when you're pushing your vehicle a bit harder. The silver finish not only looks good but also helps protect the spring from corrosion. When setting up your coilovers, ensuring the spring length and inside diameter match your shock body is key for proper function and safety.
