INSTALLATION GUIDE
Upgrade your C5/C6 Corvette to a true performance suspension with QA1’s MOD Series front coilover system. This kit replaces the factory leaf spring setup with fully adjustable coilovers, giving you complete control over ride height, handling, and overall performance.
Designed for serious street and track use, these 4-way adjustable shocks let you fine-tune high-speed compression, low-speed compression, rebound, and low-speed bleed. That means you can dial in aggressive handling for the track, then soften things up for comfortable street driving—all with precision control.
MOD Series shocks feature modular valve packs, allowing you to change valving without removing the shocks or exposing internal fluid to contamination. This makes advanced tuning faster, cleaner, and more efficient for high-performance builds.
A nitrogen-charged piggyback reservoir ensures consistent damping performance, even under extreme conditions, while still fitting within the factory suspension layout. Installation is fully bolt-in using factory mounting points, requiring only basic hand tools.
Ride height is easily adjustable, allowing you to lower your Corvette, reduce center of gravity, and properly corner balance the car for maximum performance.
- Base models: approximately 1"–2" drop
- Z06 models: approximately 0.5"–1.5" drop
Multiple spring rate options are available:

- Firm springs: best for track-focused builds
Installation Notes:
