This 12-inch long, 2-1/2 inch inner diameter coilover spring is made from chrome silicon, a strong material that allows for maximum travel. It's rated at 170 pounds per inch, meaning it will compress 1 inch under 170 pounds of force, giving you a firm but responsive feel for performance driving.

QA1 builds these springs to be as light as possible while still offering superb performance. They're finished with a durable black powder coat to resist corrosion and look good. Plus, QA1 backs them with a lifetime guarantee, ensuring they'll stay within 2% of their original free height, so you can count on consistent performance over time.
