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

A 350 lb/in spring rate means that for every inch the spring is compressed, it will exert 350 pounds of force. A higher rate like this generally results in a firmer ride and can improve handling by reducing body roll, especially during cornering or when carrying extra weight.

What is the inner diameter (ID) of this spring?

This FOX coilover spring has an inner diameter of 2.5 inches. This measurement is critical for ensuring it fits correctly onto the shock body of your FOX coilover assembly.

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 the complete coilover kit or purchased separately.

Product Details

When you're rebuilding the front suspension on your vehicle and need to dial in the ride height and spring rate, a quality coilover spring is essential. This 16-inch long spring from FOX has a 2.5-inch inner diameter and a 350 lb/in rate, designed to work with many FOX coilover systems. Getting the right spring rate helps ensure your suspension performs as intended, whether you're on the street or tackling rougher terrain.

This spring is constructed from strong steel and finished in silver. The 350 lb/in rate offers a firmer feel than stock springs, which can be beneficial for improved handling and reduced body roll, especially if you've added weight to your vehicle or are looking for a more responsive feel. It's a well-built component that contributes to the overall performance and adjustability of your FOX coilovers.
