QA1 MG507-11250C MOD Series Double Adjustable Pro-Coil Coilover Kit with Remote Canister and 250 lb/in Spring

The QA1 MG507-11250C is a MOD Series Pro-Coil aluminum coilover kit featuring a double-adjustable stock-mount shock with remote canister and an 11-inch, 250 lb/in large tapered flat spring. Engineered for serious performance builds, this kit delivers an industry-leading level of tunability for drag racing, pro-touring, and street performance applications.

The defining feature of the MOD Series is QuickTune Technology — dry modular valve packs that can be swapped out to completely revalve the shock without removing it from the car and without interrupting the oil path. This eliminates the risk of debris or air contamination during revalving, a first in the industry.

Once the desired valve pack is installed, the independent double-adjustable design with low-speed bleed allows fully independent fine-tuning of compression and rebound damping. This combination of swappable valve packs and on-car adjustability gives racers and enthusiasts an unprecedented range of force curve capability to respond to changing track conditions.

The nitrogen-charged remote canister configuration provides installation flexibility in tight engine bays. The base eyelet is indexable, allowing the shock body and canister to be repositioned to the optimal angle for clearance. The fully threaded aluminum body enables ride height adjustment to dial in stance and corner weight balance.
