QA1 MG501-10500C MOD Series GM Front Pro Coil System Double Adjustable Remote Canister 500 lb/in

The QA1 MG501-10500C MOD Series GM Front Pro Coil System is a double-adjustable coilover shock kit engineered for high-performance drag racing, pro-touring, and street performance builds. Featuring QA1's multi-patent-pending MOD Series technology, this system delivers an unprecedented level of suspension tunability without compromise.

At the heart of this system is QuickTune Technology — dry modular valve packs that allow complete revalving of the shock without removing it from the vehicle, interrupting the oil path, or exposing the internals to debris and air contamination. Medium compression and rebound valve packs are included as standard, with soft and firm valve packs available separately.

Key Features:

• Double adjustable design with low-speed bleed — provides fully independent control over compression and rebound characteristics
• Remote canister nitrogen-charged reservoir — available in piggyback or remote configuration for installation flexibility in tight spaces; indexable base eyelet allows repositioning for optimal shock and canister placement
• Threaded billet aluminum shock body — enables precise ride height adjustment and weight balance tuning
• Specially designed 10" large tapered flat spring — 500 lb/in rating; conical design seats the lower end on the shock and the upper end in the original frame spring bucket for increased energy storage and weight transfer
• Compressed height: 10.13" | Extended height: 15"
• High-travel spring design — fewer coils and smaller wire diameter reduce unsprung weight and improve suspension response
• Easy bolt-in installation using stock mounting locations and stock mount configuration
• 100% dyno-tested and serialized
• Serviceable and rebuildable by QA1 authorized service centers
• Proudly made in Lakeville, MN, USA

The QA1 MG501-10500C Pro Coil System is sold as a pair and is suitable for applications ranging from casual street driving to hardcore drag race and autocross competition. Mounting adjustability accommodates a variety of vehicle configurations for a precise, race-ready fitment.
