QA1 MG401-10600A Pro-Coil MOD Series Double Adjustable Front Coilover Kit 600 lb/in

The QA1 MG401-10600A Pro-Coil MOD Series Coilover Kit is a premium front coilover shock system engineered for high-performance street and race applications. This double adjustable aluminum shock kit features a remote canister design and is built around QA1's exclusive QuickTune Technology for unmatched on-car tunability.

At the heart of the MOD Series is the ability to completely re-valve the shock without removing it from the vehicle. Dry modular valve packs swap out quickly and cleanly, without interrupting the oil path or exposing the shock to debris or air contamination. Medium compression and rebound valve packs are included as standard, with soft and firm packs available separately.

Once the preferred valve packs are installed, the double adjustable design with adjustable low-speed bleed provides fully independent control over both compression and rebound characteristics, enabling a wide force curve capability and a precise level of damping tunability suited to any driving condition.

The fully threaded shock body allows for ride height adjustment to dial in the perfect stance or fine-tune corner weight balance. The nitrogen-charged remote canister mounts separately to ease installation in tight spaces, and the indexable base eyelet can be repositioned to optimize both shock and canister placement. Every QA1 MOD Series shock is 100% dyno tested, serialized, and proudly manufactured in QA1's Lakeville, Minnesota facility.

This kit includes a 10-inch tapered pigtail spring rated at 600 lb/in, specially designed for QA1 Pro-Coil systems with fewer coils and a smaller wire diameter for increased travel, reduced unsprung weight, and faster suspension response.
