The QA1 Pro Coil front coil‑over system delivers single‑adjustable damping with ride‑height control for front suspension upgrades. This kit includes a 10" spring rated 400 lb/in and a fully threaded body to dial in stance and weight distribution. Lightweight high‑travel springs reduce unsprung weight and increase travel, while the bolt‑in design fits factory or QA1 tubular control arms and is serviceable by authorized QA1 centers.
