The QA1 Pro Coil front coil‑over system pairs single‑adjustable damping with a high‑travel spring to improve front suspension response. This kit includes a 9" spring rated 650 lb/in and a threaded body for ride‑height adjustment so you can tune stance and weight distribution. The lightweight spring design increases travel and reduces unsprung mass, and the bolt‑in installation is compatible with factory or QA1 tubular control arms.
