QA1 MG507-09650D MOD Series Pro-Coil Double Adjustable Coilover Kit with Remote Canister 650 lb Spring

The QA1 MG507-09650D is a MOD Series aluminum Pro-Coil coilover kit featuring a double-adjustable shock with low-speed bleed and a remote nitrogen canister. Designed for high-performance street and race applications, this kit delivers an exceptional level of suspension tunability straight from the factory.

At the heart of the system is QA1's multi-patent-pending QuickTune Technology — dry modular valve packs that can be swapped out in minutes while the shocks remain on the car, without interrupting the oil path or exposing the shock to debris and air contamination. Medium compression and rebound valve packs are included as standard, with soft or firm packs available separately.

Once the desired valve pack is installed, the double-adjustable design with independent low-speed bleed control allows fully independent fine-tuning of both compression and rebound characteristics for an expansive force curve and unmatched tunability.

Key Features:

• MOD Series double-adjustable shock with adjustable low-speed bleed
• Lightweight aluminum shock body construction
• Remote nitrogen-charged canister for installation flexibility in tight spaces
• Indexable base eyelet — reposition mounting angle without removing the shock
• Fully threaded body for precise ride height adjustment
• Includes 9" large pigtail spring rated at 650 lb/in
• Compressed height: 9.63" | Extended height: 14.5"
• 100% dyno-tested and serialized at QA1's Lakeville, Minnesota facility
• Stock-mount configuration

The included American-made lightweight high-travel spring features fewer coils and a smaller wire diameter, resulting in increased suspension travel and reduced unsprung weight for faster, more responsive handling. This kit is a complete solution for enthusiasts seeking professional-grade coilover performance.
