The Godspeed Project Mono-AIR Strut Kit is the premier suspension solution for enthusiasts looking to bridge the gap between performance handling and air-ride versatility. Engineered as a direct bolt-on replacement for your factory struts, this kit allows you to achieve a slammed aesthetic at the touch of a button without sacrificing the structural integrity of your vehicle.
Each kit features performance-tuned mono-tube shocks with 32 stages of rebound damping adjustment. This puts you in total control—soften the damping for a smooth daily commute or stiffen it for high-speed stability and precision.
To ensure long-term reliability, we utilize heavy-duty rubber air bags constructed from premium compounds designed to resist drying and cracking. When paired with our corrosion-resistant hardware, the Mono-AIR system provides a durable, high-performance air suspension that stands up to the elements.
