What is a spring rate and why does it matter?

The spring rate, measured in pounds per inch (lbs/in), indicates how much force is needed to compress the spring by one inch. A higher spring rate, like the 700 lbs/in on this spring, means the spring is stiffer and will resist compression more, leading to a firmer ride and better control of body roll.

What does the inner diameter (ID) refer to?

The inner diameter is the measurement across the inside of the spring. This 2.5-inch ID is crucial for ensuring the spring fits correctly onto the shock absorber body or perch of your coilover assembly.

What is the purpose of the silver finish?

The silver finish on this Fox coilover spring is primarily for aesthetics, providing a clean and professional look to your suspension components. It can also offer some basic protection against corrosion.
