What is included with this product?

This product is a single QA1 high travel coilover spring. It does not include any other suspension components or hardware.

What does the spring rate mean for my vehicle?

A 300 lb/in spring rate means that for every inch the spring is compressed, it takes 300 pounds of force. This rate is often chosen for improved handling and reduced body roll in performance applications.

What is the benefit of a tapered end on a coilover spring?

A tapered end allows the spring to sit securely in the spring perch or seat, often providing a more stable connection and preventing unwanted movement or noise.
