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

The spring rate indicates how much force is needed to compress the spring by one inch. A 650 lbs/in rate means it will take 650 pounds of force to compress the spring one inch. This rate generally provides a firmer ride and better control over body roll compared to softer springs.

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

This coil spring has an inner diameter of 2.5 inches. This is a common size for many aftermarket and some OEM coilover shock absorbers, but it's always best to measure your shock body to ensure a proper fit.

What is the free length of this spring?

The free length of this Ridetech coil spring is 7 inches. This is the length of the spring when it is not under any load or compression.
