What is the spring rate and what does it mean for my vehicle?

This spring has a rate of 350 lbs/in. This means it takes 350 pounds of force to compress the spring by one inch. A higher spring rate generally offers a firmer ride and better control during spirited driving or cornering.

What is the 'pigtail' end on this spring?

The pigtail end is a common feature on many coilover springs. It's a tightly wound loop at one end of the spring that helps it seat properly and securely into the spring perch or mounting hardware on your suspension.

What does the lifetime guarantee cover?

QA1 guarantees that these springs will remain within 2% of their original free height for the life of the product. This ensures consistent performance and ride height over many years of use.
