Its high-travel design uses a smaller-diameter, high-tensile chrome silicon wire with fewer coils than a standard coil spring, spacing the coils farther apart so the spring can compress further before reaching coil-bind - giving you more usable suspension travel without bottoming out.\u003c\/p\u003e\u003cp\u003eBecause the spring rate is linear rather than progressive, it stays consistent throughout the entire stroke, so the suspension behaves the same way at the top of travel as it does deep into compression - a trait racers and street builders alike tend to prefer for predictability. The lightweight chrome silicon construction also helps cut unsprung weight, letting the suspension react faster over bumps and transitions.\u003c\/p\u003e\u003cp\u003eEach spring is cold-wound, heat-treated, and shot-peened for long-term fatigue resistance, then ground square at both ends for accurate, consistent seating in the coilover perch. It's backed by QA1's lifetime warranty against free-height and rate deviation, and works well as a direct swap or upgrade spring for any 2.5 in. I.D. coilover shock - front or rear, street or track.\u003c\/p\u003e\u003cmeta name=\"description\" content=\"Upgrade your suspension with QA1's 10in. High Travel Coilover Spring.
