QA1 MG507-10550C MOD Series Double Adjustable Pro-Coil Aluminum Coilover Kit with Remote Canister 10in 550lb

The QA1 MG507-10550C is a MOD Series double-adjustable Pro-Coil aluminum coilover kit featuring a remote canister and stock mount configuration. Engineered for serious street performance and racing applications, this kit delivers an exceptional level of ride tunability and height adjustability in a bolt-in package.

QuickTune Modular Valve Technology:

At the heart of the MOD Series is QA1's patented QuickTune Technology — a dry, modular valve pack system that allows complete re-valving in minutes while the shocks remain mounted on the vehicle. Medium compression and rebound valve packs are included as standard, with optional soft and firm packs available separately. Once valve packs are set, the independent double-adjustable low-speed bleed design allows precise fine-tuning of compression and rebound characteristics independently for maximum control over ride quality and handling balance.
