QA1 2-1/2in ID High Travel Spring - 14in Length x 110lbs/in - Silver Powder Coated

QA1 is known for its performance suspension components, and these high travel springs are a great example of their commitment to quality. If you're building or rebuilding a coilover setup, these springs are designed to give you the most out of your suspension travel. They use a specially designed chrome silicon alloy wire, which is high-tensile, allowing for fewer coils and a smaller wire diameter. This means the springs themselves are lighter, which helps reduce unsprung weight and allows your suspension to react faster to changes in the road.

The design of these springs also gives them increased travel because there's more space between the coils. QA1 carefully heat-treats and shot-peens the material, which greatly improves fatigue life. You can even compress these springs down to coil-bind without changing their spring rate or free height. They're finished with a silver powder coat and ground at both ends for straight, consistent operation. Plus, QA1 backs them with a lifetime guarantee to stay within 2% of their original free height and rate under normal use.
