What is the spring rate of this QA1 coilover spring?

This QA1 coilover spring has a spring rate of 500 lbs per inch. This means it takes 500 pounds of force to compress the spring by one inch.

What does the 'pigtail end' design do?

The pigtail end is a design feature that allows the spring to coil down more tightly at the end. This helps to maximize the amount of suspension travel you can achieve with the spring.

What is the lifetime guarantee on this spring?

QA1 guarantees this spring for life to remain within 2% of its original free height. This ensures consistent performance and ride height over the life of the spring.
