Product Details

Dialing in your spring rate for the way your vehicle is built, your specific needs, and driving preferences is just as critical as making sure your dampers are tuned to your specs. Whether you are trying to dial in ride height or fine tune bump compliance and handling, QA1 makes it easy by offering numerous spring rates from 80 to 600 lbs/in, so the right rate is a click away. QA1 Springs are made of a Chrome Silicon Steel that gets cold wound, heat treated, shot peened, and flat ground for high strength, maximum consistency, accurate fitment, and an overal longer life. Then for further protection from the elements they are powder coated silver or polished and chrome plated depending on your style preference.
