The QA1 GM Pro Front MOD Series coil‑over combines a double‑adjustable MOD shock with a 10" large tapered flat spring rated at 750 lb/in for front GM applications, delivering stiff wheel control for heavy‑duty track or drag setups. QuickTune dry modular valve packs allow rapid on‑car revalving without opening the shock, while 4‑way high/low speed bleed and remote or piggyback canister options broaden tuning. The unit is 100% dyno tested and serialized, with 9.63" compressed and 14.5" extended heights.
