What is a coilover spring rate?

The spring rate, measured in pounds per inch (lb/in), indicates how much force is needed to compress the spring by one inch. A higher number means a stiffer spring, while a lower number means a softer spring. This 500 lb/in spring is a moderate rate suitable for many applications.

Does this spring come with any hardware?

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

How do I know if this spring is right for my vehicle?

Determining the correct spring rate depends on your vehicle's weight, intended use, and the specific shock body it will be used with. It's recommended to consult your vehicle's suspension specifications or a suspension professional to ensure this 500 lb/in spring is appropriate for your setup.

About this part

Product Details

This listing is for a single Fox coilover spring. You get one 12-inch long spring with a 3-inch inside diameter, rated for 500 pounds per inch of compression. It comes in a silver finish.

This spring is designed to work with Fox shocks and coilovers, offering a specific spring rate that's crucial for controlling suspension travel and ride height. The 500 lb/in rate is a popular choice for many applications where a balance between off-road capability and on-road comfort is desired. Proper spring selection ensures your suspension performs as intended, absorbing impacts and maintaining tire contact with the ground.

When choosing a spring, consider the overall weight of your vehicle and how you use it. A spring rate that's too soft can lead to bottoming out, while one that's too stiff can make the ride harsh. This Fox spring is a well-built component that can be a solid option for rebuilding or upgrading your existing coilover setup.
