What is a coilover spring rate and why does it matter?

The spring rate, measured in pounds per inch (lb/in), indicates how much force is needed to compress the spring. A higher spring rate, like this 175 lb/in spring, means the spring is stiffer, which can lead to improved handling and reduced body roll.

What does the 'ID' measurement refer to?

ID stands for Inner Diameter. This measurement is crucial for ensuring the spring fits correctly onto the shock body or threaded sleeve of your coilover assembly. This spring has a 2.5-inch inner diameter.

Can I mix and match spring rates on my coilovers?

It is generally recommended to use the same spring rate on both sides of an axle for consistent handling and suspension performance. Using different rates can negatively affect your vehicle's balance and stability.

About this part

Product Details

If you're looking to fine-tune your suspension's ride height and spring rate, a replacement coilover spring like this one from FOX is a solid option. This spring measures 10 inches long with a 2.5-inch inner diameter and a 175 lb/in rate, designed to work with many FOX shocks and other coilovers that accept these dimensions.

FOX is known for its suspension components, and this spring is built to handle the demands of off-road or performance driving. The 175 lb/in rate offers a firmer feel than stock springs, which can help reduce body roll during cornering and improve responsiveness on rough terrain. Its silver finish not only looks good but also offers a layer of protection against the elements.

When replacing coilover springs, it's important to ensure the dimensions and spring rate match your shock body and intended use. This spring is a direct replacement for many FOX applications, allowing you to dial in your suspension setup precisely.
