Shock Monotube 3-5 Valve

The QA1 Shock Monotube 3-5 Valve is a precision rear shock absorber designed for builders and enthusiasts looking for advanced suspension control on custom and modified vehicles. This monotube design offers superior damping characteristics across various road conditions, making it ideal for tuning street rods, competition builds, or high-performance street cars.

The monotube construction means the piston rod and pressure tube function as a single sealed unit, eliminating the need for an external reservoir. The 3-5 valve configuration allows for multi-stage damping, with independent compression and rebound valving that adjusts across different velocity ranges. This design ensures the shock responds effectively to both small bumps at highway speeds and aggressive cornering loads.

Mechanics and fabricators commonly specify QA1 monotube shocks for applications such as drag racing, autocross, road course, and street performance. The shock's lightweight construction and compact collapsed length make it suitable for rear shock applications where performance and weight savings are critical.
