The QA1 high travel coil-over spring is a 2-1/2 inch inner diameter spring with a 10 inch free length and a 200 lb/in spring rate. It is wound from high-tensile chrome silicon alloy wire, which allows fewer coils and a smaller wire diameter, so the spring is lighter and travels farther while reducing unsprung weight and reacting faster. Both ends are squared and ground for straight, consistent operation, and each spring is marked with its free length and rate. The spring can be compressed to coil bind without affecting rate or free height, and it is backed by a lifetime guarantee to stay within 2 percent of its original rate and free height under normal use.
