About this part

Product Details

This listing is for a single FOX coilover spring. You get one silver spring measuring 12 inches long with a 2.5-inch inner diameter, rated at 400 pounds per inch of spring rate. This spring is designed to work with FOX 2.5-inch diameter body coilovers.

A 400 lb/in spring rate offers a noticeable increase in damping control over stock springs, making it a solid option for vehicles that see more aggressive driving or carry extra weight. The silver finish is a nice touch, and FOX is known for well-built suspension components that perform reliably.

When replacing coilover springs, it's important to ensure you have the correct spring rate for your vehicle's weight and intended use. Always refer to your specific FOX coilover kit's documentation for proper installation and any recommended spring pairings.
