What does the spring rate (250 lb/in) mean for my vehicle's performance?

A 250 lb/in spring rate means that for every inch the spring is compressed, it exerts 250 pounds of force. A higher spring rate generally leads to a stiffer ride and less body roll in corners, while a lower rate offers a softer ride. This rate is often chosen for a balance between comfort and control.

What is the inner diameter and length of this spring?

This coilover spring has an inner diameter of 3 inches and a length of 16 inches. It's important to ensure these dimensions match the specifications of your existing Fox shock absorber or the intended application.

Does this spring come with any hardware or retainers?

This product is for the coilover spring only. Any necessary hardware, such as spring perches, retainers, or upper mounts, would typically be sold separately or may be reusable from your existing coilover assembly.

Product Details

This is a Fox 16-inch long, 3-inch inner diameter coilover spring rated at 250 pounds per inch. It is finished in silver. This spring is designed to work with specific Fox shock bodies and is a replacement or upgrade part for custom suspension setups. The spring rate determines how much force it takes to compress the spring, directly impacting your vehicle's ride height and handling characteristics.

The 250 lb/in rate is a moderately stiff spring, often used in applications where a balance between ride comfort and improved body control is desired. For example, if you're rebuilding the front coilovers on a vehicle that sees a mix of street driving and occasional off-road use, this spring rate can offer a noticeable improvement in reducing body roll during cornering while still providing a comfortable ride over bumps. Ensure your existing shock body is designed to accept a 3-inch inner diameter spring and has the correct spring perch dimensions for a 16-inch length.
