QA1 MG401-10350A Pro-Coil MOD Series Double Adjustable Coilover Kit with Remote Canister

The QA1 MG401-10350A Pro-Coil MOD Series Coilover Kit is a high-performance double adjustable coilover system designed for serious street and track applications. Featuring an aluminum shock body with a remote canister, this kit delivers the precision damping control demanded by drag racing, pro-touring, and street performance builds.

The MOD Series differentiates itself with QuickTune technology, allowing dry modular valve packs to be swapped without removing the shock from the vehicle — enabling rapid re-valving at the track or in the garage. The double adjustable design provides independent control over low-speed compression and rebound characteristics, letting drivers fine-tune handling for varying track and road conditions.

Key Features:

• Double adjustable damping — independent low-speed compression and rebound bleed adjustment
• QuickTune modular valve packs — re-valve without removing the shock from the vehicle
• Lightweight billet aluminum shock body with remote canister for improved heat dissipation
• Threaded shock body for precise, tool-free ride height adjustment
• Compressed height: 8.63 inches | Extended height: 12.63 inches
• Includes 10-inch tapered pigtail coil spring rated at 350 lb/in
• Medium compression and rebound valve packs included; soft and firm packs available separately
• 100% dyno tested and serialized
• Serviceable and rebuildable by QA1 Authorized Service Centers
• Made in the USA

Suitable for drag racing, street performance, autocross, road racing, and street rod applications, the MG401-10350A kit is sold as a complete coilover assembly with the spring included. The stock-mount configuration simplifies installation in compatible platforms.
