The QA1 Pro Coil front coil‑over system provides single‑adjustable damping and threaded body ride‑height tuning for front suspension upgrades. This version ships with a 10" spring rated 500 lb/in to support firmer spring rates while retaining travel. High‑travel spring geometry reduces unsprung weight and improves response; the assembly is a bolt‑in solution compatible with factory or QA1 tubular control arms and is serviceable by QA1 authorized centers.
