The QA1 Pro Coil front coil‑over system offers single‑adjustable damping and threaded body ride‑height adjustment to help tune front suspension balance. Included is a 10" spring rated 500 lb/in designed for higher spring rates while maintaining travel. The lightweight, high‑travel spring profile helps reduce unsprung mass and improve response; the assembly is a bolt‑in solution intended to work with factory or QA1 tubular control arms and serviceable by QA1 service centers.
