What does the spring rate (650 lbs/in) mean for my vehicle's ride?

A spring rate of 650 pounds per inch means that it takes 650 pounds of force to compress the spring by one inch. A higher spring rate generally results in a stiffer ride and can improve handling by reducing body roll, but may also make the ride less comfortable over bumps.

Will this spring fit my existing coilover shocks?

This spring has a 2.5-inch inner diameter and is 12 inches long. You will need to ensure your existing coilover shock bodies are designed to accept these specific dimensions for a proper fit.

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 assembly or purchased separately.

About this part

Product Details

If you're looking to fine-tune your suspension's ride height and stiffness, a new coilover spring is a key component. This 12-inch long spring from Fox has a 2.5-inch inner diameter and a spring rate of 650 pounds per inch, offering a well-built option for adjusting your vehicle's stance and handling characteristics. The silver finish adds a clean look to your suspension setup.

Fox is known for its suspension components, and this spring is built to match that reputation. The 650 lb/in rate is a popular choice for many applications where a firmer ride is desired without being overly harsh, providing improved control during cornering and over rough terrain. Its 12-inch length and 2.5-inch inner diameter are standard dimensions for many coilover shock bodies, making it a straightforward replacement or upgrade.
