QA1 MG401-10750C MOD Series Pro-Coil Double Adjustable Coilover Kit 750 lb Remote Canister

The QA1 MG401-10750C is a MOD Series Pro-Coil aluminum coilover kit featuring double-adjustable valving with low-speed bleed and a remote nitrogen canister. Engineered for high-performance street, drag racing, pro-touring, autocross, and road racing applications, this kit delivers an unmatched level of suspension tunability without the need for cutting or welding.

At the heart of the system is QA1's QuickTune Technology — a patent-pending modular dry valve pack design that allows complete revalving in minutes while the shock remains on the car, without interrupting the oil path or exposing the shock internals to debris or air contamination. Once the desired valve pack is installed, the independent 24-click compression and rebound adjusters with low-speed bleed allow fine-tuned control over ride quality and weight transfer characteristics.

Key Features:

• MOD Series double-adjustable coilover shock with low-speed bleed
• QuickTune Technology: swappable dry modular valve packs — revalve without removing the shock from the car
• 24-click independent compression and rebound adjustment
• Large solid piston with blow-off valve for improved driver feel and control
• Lightweight billet aluminum shock body construction
• Remote nitrogen-charged canister for ease of installation in tight spaces
• Indexable base eyelet — reposition for optimal knob access and mounting flexibility
• Fully threaded body for precise ride height adjustment
• Compressed height: 8.63 in. | Extended height: 12.63 in.
• Includes 10 in. large tapered flat (large diameter, flat upper end) spring rated at 750 lb/in.
• Kit includes Torrington bearings
• Medium compression and rebound valve packs included; soft or firm packs available separately
• 100% dyno tested and serialized
• Serviceable and rebuildable by QA1 Authorized Service Centers
• Made in the USA — QA1's Lakeville, Minnesota facility
• Sold in pairs

QA1's Pro-Coil high-travel springs feature fewer coils and a smaller wire diameter than conventional springs, increasing travel by maximizing the distance between coils. This reduces unsprung weight and allows the suspension to react faster for optimized handling performance across a wide range of spring rate options.
