QA1 12in X 700 Lbs/in. Black Powder Coat Spring CR-SI High Travel 2-1/2in ID

This is a QA1 12-inch coilover spring, rated at 700 pounds per inch of travel. It's made from CR-SI steel for durability and features a black powder coat finish for corrosion resistance. The spring has a 2-1/2 inch inside diameter, making it suitable for many popular coilover shock bodies.

QA1 uses CR-SI steel, a strong material known for its ability to handle repeated compression and extension without losing its shape or spring rate. The 700 lb/in rating means it will provide a firm ride, often chosen for performance applications where reduced body roll is desired. The 12-inch length allows for a good range of suspension travel, and the black powder coat helps protect the spring from road debris and moisture.
