What is the spring rate of this FOX coilover spring?

This FOX coilover spring has a spring rate of 300 pounds per inch (300 lb/in). This rate is generally firmer than stock suspension springs and is often chosen for improved handling and reduced body roll.

What size coilover shock does this spring fit?

This spring is designed to fit FOX 2.5-inch diameter coilover shocks. It's important to ensure your shock body matches this diameter for proper fitment and function.

How is the spring installed on the coilover?

This spring slides onto the coilover shock body. The ride height and preload are adjusted using the threaded collars on the shock body itself, not by compressing the spring during installation.

About this part

Product Details

When you're rebuilding the front suspension on your vehicle and need to set the ride height and spring rate for your FOX coilovers, a new spring is key. This FOX coilover spring measures 14 inches long with a 2.5-inch inner diameter and a 300 lb/in spring rate, finished in a silver powder coat.

This spring is designed to work with FOX 2.5-inch diameter coilover shocks. The 300 lb/in rate offers a firmer ride than stock, which can help reduce body roll during cornering and improve handling on rough terrain. The silver finish not only looks good but also adds a layer of protection against corrosion.

When installing, remember that spring preload is adjusted on the shock body itself, not by compressing the spring. Ensure you have the correct tools to safely handle and install the spring onto your coilover shock assembly.
