The QA1 GM Pro Front MOD Series coil‑over system pairs a MOD Series double‑adjustable shock with a 10" tapered flat spring rated 400 lbs/in to give wide tunability for front suspension setups. QuickTune dry modular valve packs let you revalve the shock without opening it, while 4‑way bleed adjustment and remote or piggyback canister options refine compression and rebound. Compressed height is 8.63" and extended is 12.63"; each unit is dyno tested and serialized.
