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

A spring rate of 350 pounds per inch means that for every inch the spring is compressed, it will exert 350 pounds of force. A higher spring rate generally results in a firmer ride and less body roll during cornering, while a lower rate offers a softer, more comfortable ride.

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

This Fox coilover spring has an inner diameter of 2.5 inches. This measurement is important to ensure it fits correctly onto your specific coilover shock body.

Does this spring come with any hardware?

This product is for the coilover spring only. Any necessary hardware, such as spring perches or retainers, would typically be part of the complete coilover assembly or sold separately.
