What is the spring rate and what does it mean?

The spring rate is 350 pounds per inch (350 lb/in). This means it takes 350 pounds of force to compress the spring by one inch. A higher spring rate generally results in a firmer ride and less body roll.

What does the 2.5-inch ID refer to?

ID stands for Inner Diameter. The 2.5-inch ID means the hole in the center of the spring is 2.5 inches across. This is a common size for many aftermarket shock absorbers and coilover bodies.

Is this spring sold individually or as a set?

This product listing is for a single coil spring. If you are building a suspension system, you will likely need to purchase multiple springs to match your vehicle's axle configuration.

Product Details

What you get here is a single Ridetech coil spring, measuring 14 inches in free length with a spring rate of 350 pounds per inch. It has a 2.5-inch inner diameter, which is a common size for many aftermarket shock bodies. This spring is designed for universal applications, meaning it's intended for custom builds or as a replacement where specific dimensions and rates are needed.

This spring is well-built for its intended purpose. The 350 lb/in rate offers a firmer ride than many stock springs, which can be beneficial for improved handling and reduced body roll, especially in performance-oriented or custom suspension setups. The 14-inch length is also a key dimension to consider when setting up ride height and suspension travel in a custom application.
