QA1 M431CR MOD Series Coilover Shock Remote Canister 7 Inch Spring

The QA1 M431CR is a high-performance MOD Series coilover shock with remote canister, designed specifically for drag racing, pro-touring, and high-performance handling applications. This innovative shock features QA1's multi-patent-pending QuickTune Technology, which allows racers to completely revalve the shock in minutes while it remains mounted on the vehicle—an industry first that saves valuable time and money at the track.

Key Features:

• QuickTune Technology with modular valve packs for complete revalving without removing the shock from the car
• Double adjustable design with 24-click independent high-speed compression and rebound adjustment
• Adjustable low-speed bleed circuits (3.5 turns) for fine-tuning slow chassis movements
• Medium compression and rebound valve packs included (soft and firm packs available separately)
• Large solid piston with blow-off valve for improved driver feel and control up to 1,600 lbs of force
• Remote nitrogen-charged canister connected by 18-inch hose for installation flexibility in tight spaces
• Indexable base eyelet repositionable in 72-degree increments for optimal shock and canister placement
• Accepts 7-inch coilover springs
• 100% dyno tested and serialized
• Proudly made in Lakeville, Minnesota

The MOD Series shock achieves an expansive force curve capability and unprecedented tunability, allowing racers to quickly adapt to changing track conditions, weather, and configurations without opening the shock or interrupting the oil path. The remote canister configuration provides maximum mounting flexibility in nearly any chassis setup.
