The QA1 Pro Coil front coil‑over system combines single‑adjustable damping with ride‑height tuning via a threaded body. This version includes a 10" spring rated 750 lb/in for substantial spring stiffness while retaining travel. High‑travel spring construction reduces unsprung weight and enhances suspension response; the bolt‑in kit is compatible with typical front control arms and is serviceable by QA1 authorized centers, with US manufacturing pedigree.
