What does the spring rate (100 lbs/in) mean for my vehicle?

The spring rate indicates how much force is needed to compress the spring by one inch. A 100 lb/in rate means it takes 100 pounds of force to compress the spring one inch. This rate is often chosen for improved body control and handling compared to stock springs.

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

This coilover spring has a 3-inch inner diameter, which is a standard size for many performance shocks. It measures 10 inches in free length, meaning its length when not under load.

Is this spring compatible with all Fox shocks?

This spring is designed to work with Fox shocks that utilize a 3-inch ID spring and are intended for a 10-inch length spring. Always verify the specific requirements for your Fox shock model to ensure proper fitment and function.
