QA1 MG501-10600A Pro-Coil MOD Series Double Adjustable Coilover Kit with Remote Canister 600 lb/in

The QA1 MG501-10600A Pro-Coil MOD Series coilover kit is a double adjustable front coil-over shock system featuring a remote canister design and a 600 lb/in tapered pigtail spring. With a compressed height of 10.13 inches and an extended height of 15 inches, this kit delivers a wide range of suspension tunability engineered for high-performance street and track applications.

At the heart of this system is QA1's QuickTune Technology — dry modular valve packs that can be completely swapped out while the shock remains on the car. This industry-first design allows full revalving without interrupting the oil path or exposing the shock internals to debris or air contamination. Medium compression and rebound valve packs are included as standard, with soft and firm packs available separately for further tuning flexibility.

Key Features:

• Double adjustable MOD Series shock with independent low-speed bleed adjustment for fully independent control of compression and rebound characteristics
• QuickTune Technology — revalve in minutes without removing the shock from the car
• Nitrogen-charged remote canister for optimal performance in tight installation spaces
• Indexable base eyelet — unbolt and reattach at the ideal angle for best shock and canister placement
• Includes 10-inch tapered pigtail spring rated at 600 lb/in
• Kit includes Torrington (thrust) bearings
• Compressed height: 10.13 in. | Extended height: 15 in.

Suitable for drag racing, street performance, autocross, road racing, and pro-touring builds, the QA1 MOD Series coilover system provides an expansive force curve capability and an unprecedented level of suspension tunability to meet the demands of changing track conditions and configurations.
