QA1 MG501-10650C Pro-Coil MOD Series Double Adjustable Coilover Kit with Remote Canister, 10in. Spring 650 lb./in.

The QA1 MG501-10650C is a Pro-Coil MOD Series double adjustable coilover kit featuring a stock mount shock body with a remote nitrogen-charged canister and a 10-inch large tapered flat coil spring rated at 650 lb./in. The shock has a compressed height of 10.13" and an extended height of 15", delivering a precise, tunable suspension solution for high-performance street and race applications.

QuickTune Modular Valve Technology:

At the core of the MOD Series is QA1's patent-pending QuickTune Technology — dry modular valve packs that can be swapped out in minutes while the shocks remain installed on the vehicle. This re-valving process never interrupts the oil path or opens the shock to debris or air contamination. Medium compression and rebound valve packs are included as standard; soft or firm packs are available separately for further tuning.

Key Features:

• Double adjustable design with independent low-speed bleed control of compression and rebound valving
• Lightweight billet aluminum shock body construction
• Remote nitrogen-charged canister for ease of installation in tight spaces; base eyelet is indexable for optimal shock and canister placement
• Threaded shock body for ride height adjustability
• Includes 10" large tapered flat spring rated at 650 lb./in.
• Compressed height: 10.13" | Extended height: 15"
• 100% dyno-tested and serialized at the factory
• Serviceable and rebuildable by QA1 Authorized Service Centers
• Made in the USA

Suited for drag racing, pro-touring, autocross, road racing, and high-performance street rod builds, the MG501-10650C delivers an unprecedented level of tunability to adapt to changing track conditions and driving styles.
