What does a 150 lbs/in spring rate mean?

A 150 lbs/in spring rate means that for every inch the spring is compressed, it will resist with 150 pounds of force. This rate helps determine how stiff or soft your suspension feels.

What is the difference between free length and inner diameter?

The free length is the total length of the spring when it's not under any load. The inner diameter is the measurement across the inside of the spring, which needs to match the coilover body it's installed on.

What vehicles does this specific spring fit?

This spring is designed to fit FOX 2.5 inch diameter coilovers. It is not specific to a particular vehicle make or model, but rather the coilover assembly it is paired with.

About this part

Product Details

This is a FOX 2.640 inch TLG x 2.500 inch ID x 150 lbs/in coilover spring. It's designed to work with FOX 2.5" diameter coilovers, offering a specific spring rate for your suspension setup. Choosing the right spring rate is crucial for tuning your vehicle's ride and handling characteristics, whether you're looking for a firmer feel for off-road performance or a more controlled response on the street.

This spring features a 150 lbs/in rate, which means for every inch the spring is compressed, it will exert 150 pounds of force. This rate is a common choice for many applications, providing a balance between comfort and control. The 2.640 inch free length and 2.500 inch inner diameter ensure it fits properly within the FOX coilover body it's intended for, allowing for consistent performance and proper suspension travel.
