What does a linear spring rate mean for my suspension?

A linear spring rate means the force the spring applies increases at a constant rate as it's compressed. This offers predictable suspension response, which is beneficial for tuning performance setups.

What is the inner diameter of this spring?

This spring has an inner diameter of 61mm. This is a common size for many coilover applications, but it's always best to verify it matches your existing setup.

Do I need to buy more than one of these springs?

Yes, this product is sold individually. You will need to purchase the appropriate number of springs to match your coilover system's requirements, typically two or four.

About this part

Product Details

AST is known for making well-built suspension components, and these linear race springs are no exception. This specific spring measures 130mm in length with a spring rate of 70 Newtons per millimeter and a 61mm inner diameter. It's designed for performance applications where precise suspension control is important.

The linear spring rate means that as the spring is compressed, the force it exerts increases proportionally. This predictable behavior is crucial for tuning suspension setups for track use or spirited driving. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for builders looking to customize their suspension.

This is a single spring, so you'll need to order the correct quantity for your specific coilover setup. Ensure you match the spring rate and dimensions to your existing components or your tuning goals for optimal performance.
