QA1 2-1/2in ID High Travel Spring - 10in Length x 700lbs/in - Black Powder Coated

What you get here is a QA1 2-1/2 inch inner diameter high travel coilover spring, measuring 10 inches long with a 700 pound per inch spring rate. It's finished in a durable black powder coat to resist corrosion and looks sharp. This spring is made from chrome silicon, a strong material chosen for its ability to handle repeated compression and return to its original shape.

QA1 builds these springs to be as light as possible while still giving you maximum travel and solid performance. They're so confident in their construction that they offer a lifetime guarantee, ensuring the spring will stay within 2% of its original free height. This means you can count on consistent performance over the life of the spring. It's made in the USA, which is always a good sign of attention to detail in manufacturing.
