The QA1 Pro Coil front coil‑over system offers single‑adjustable damping and threaded ride‑height adjustment aimed at improving front suspension tuning. This variant includes an 11" spring rated 250 lb/in to provide a softer spring option with increased travel. The lightweight high‑travel spring profile increases suspension travel and responsiveness, and the assembly installs as a bolt‑in for common front setups while remaining serviceable by QA1 centers.
