What is the spring rate and why does it matter?

This spring has a rate of 450 pounds per inch (lb/in). This number indicates how much force is needed to compress the spring by one inch. A higher spring rate generally means a firmer ride and is often chosen for performance applications where reduced body roll is desired.

What does the 'high travel' and 'tapered end' design mean?

High travel means the spring is designed to allow for a greater range of suspension movement, which is beneficial for performance driving. The tapered end is a design feature that helps the spring seat properly and can prevent binding, ensuring smoother suspension action.

What is the warranty on this spring?

QA1 offers a lifetime guarantee on this spring, ensuring it will remain within 2% of its original free height throughout its life. This commitment means you can expect consistent performance from the spring over many years.
