The QA1 GM Pro Front MOD Series coil‑over brings a double‑adjustable MOD shock together with a 10" large tapered flat spring rated at 550 lb/in for front GM applications, allowing refined control over ride and handling. MOD Series hardware uses QuickTune dry modular valve packs so valving can be changed on the car without exposing the shock internals. The shock offers 4‑way high and low speed bleed, remote or piggyback canister options, is dyno tested and serialized, and measures 9.63" compressed and 14.5" extended.
