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

This spring has a rate of 400 lbs/in. This means it takes 400 pounds of force to compress the spring by one inch. A higher spring rate generally results in a stiffer suspension, which can improve handling by reducing body roll during cornering.

What is the 'pigtail' end, and why is it important?

The pigtail end is a coiled, circular shape at one end of the spring. It's designed to fit securely into specific mounting points on your vehicle's suspension, ensuring the spring stays properly seated and functions as intended.

What does the lifetime guarantee cover?

QA1 guarantees this spring for life to remain within 2% of its original free height. This means the spring is designed to resist sagging over time, maintaining its intended performance and ride height for the life of the product.
