What does a 375 lb/in spring rate mean?

A 375 lb/in spring rate means that for every inch the spring is compressed, it will exert 375 pounds of force. This rate influences how stiff or soft your suspension feels and how it handles body roll.

What is the inner diameter of this spring?

The inner diameter of this Ridetech coil spring is 2.5 inches. This is a common size for many coilover shock bodies, but it's always best to measure your existing shock to ensure a proper fit.

Does this spring come with any hardware?

This product listing is for a single coil spring only. Any associated hardware, such as spring perches or retainers, would need to be purchased separately if not already part of your existing coilover assembly.

Product Details

What you get here is a single Ridetech coil spring. It measures 12 inches in free length and has a 2.5-inch inner diameter. This spring is rated at 375 pounds per inch, meaning it will compress 1 inch under a 375-pound load. This is a common spring rate for many custom suspension setups or when rebuilding existing coilover systems.

This spring is built with a consistent rate, which helps your suspension react predictably to road conditions. The 2.5-inch inner diameter is a popular size for many coilover shock bodies, making it a versatile option for custom builds or replacements. While it's a universal part, it's often used in applications where a specific spring rate is needed for better handling or to achieve a desired ride height when paired with the right shock absorber.
