QA1 MG501-10650A Pro-Coil MOD Series Double Adjustable Front Coilover Shock Kit with Remote Canister

The QA1 MG501-10650A is a MOD Series front Pro-Coil aluminum coilover shock kit featuring a remote canister and double adjustable valving. Engineered for high-performance drag race and pro-touring applications, this kit delivers an unprecedented level of tunability to help racers respond quickly to changing track conditions and vehicle configurations.

At the heart of this system is QA1's QuickTune™ Technology—dry modular valve packs that can be swapped out using only a hex key or Allen wrench, all while the shock remains mounted on the car. This industry-first design allows complete re-valving in minutes without interrupting the oil path or exposing the shock internals to debris and air contamination.

Key Features:

• Double Adjustable Design: Fully independent control over compression and rebound characteristics, with adjustable low-speed bleed for precise tuning
• QuickTune™ Technology: Interchangeable modular valve packs swapped without removing the shock from the vehicle
• Remote Canister: Nitrogen-charged remote reservoir for improved heat dissipation and ease of installation in tight spaces
• Compressed Height: 10.13 inches
• Extended Height: 15.00 inches
• Included Spring: 10-inch tapered pigtail spring with a 650 lb/in. spring rate
• Spring Free Length: 10 inches
• Recommended Front End Weight: 2,301–2,400 lbs.
• Aluminum Construction: Lightweight yet durable shock body for reduced unsprung weight
• Stock Mount Compatible: Designed for factory-style mounting locations
• Medium compression and rebound valve packs included as standard; soft and firm packs available separately
• 100% dyno tested and serialized; proudly made in Lakeville, Minnesota

The QA1 Pro-Coil spring included with this kit features fewer coils and a smaller wire diameter than traditional coilover springs, increasing travel and reducing unsprung weight for faster suspension response. The tapered pigtail design ensures proper seating and compatibility with this MOD Series shock body.

Whether you're building a dedicated drag car, a road-course pro-tourer, or a performance street machine, the QA1 MG501-10650A gives you the tools to dial in your suspension with confidence.
