QA1 MG501-10350A MOD Series GM Front Pro Coil System 350 lb/in Double Adjustable Remote Canister

The QA1 MG501-10350A MOD Series Front Pro Coil System is a premium double-adjustable coilover shock kit engineered for high-performance drag racing, pro-touring, and handling-focused GM applications. Built around QA1's multi-patent-pending MOD Series platform, this front coilover system delivers an unmatched level of tunability to help drivers adapt quickly to changing track conditions and driving configurations.

QuickTune Technology — Revalve Without Removing the Shock:

At the heart of the MOD Series is QA1's exclusive QuickTune Technology, featuring dry modular valve packs that can be swapped out in minutes while the shock remains on the vehicle. This industry-first design allows complete 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; soft and firm packs are also available separately.

Key Features:

• Double adjustable design with independent low-speed bleed control for fully separate compression and rebound tuning
• Remote nitrogen-charged canister for flexible installation in tight engine bays; base eyelet is indexable for optimal shock and canister placement
• Fully threaded shock body for precise ride height adjustment and weight balance tuning
• Compressed height: 10.13" | Extended height: 15"
• Includes 10" tapered pigtail spring rated at 350 lb/in
• Stock upper mount configuration for straightforward installation
• American-made lightweight high-travel spring with fewer coils and smaller wire diameter for increased suspension travel and reduced unsprung weight
• 100% dyno tested and serialized; manufactured at QA1's Lakeville, Minnesota facility

The MG501-10350A is part of QA1's GM Pro Coil System lineup, designed to deliver consistent, competition-ready performance across a wide range of applications — from casual street driving to hard-core racing builds. The combination of QuickTune revalving, remote canister flexibility, and a fully threaded body makes this one of the most adjustable front coilover systems available for classic GM platforms.
