Shock Monotube 3-5 Valve

The QA1 Shock Monotube 3-5 Valve is a precision rear shock absorber engineered for vehicles requiring independent suspension tuning and responsive damping control. This monotube design delivers consistent performance across a wide range of driving conditions, from smooth highway cruising to aggressive off-road terrain, making it an essential upgrade for serious suspension builders and off-road enthusiasts who demand predictable handling and durability.

The 3-5 valving configuration allows fine-tuned compression and rebound control, critical for vehicles where weight distribution, load capacity, or driving dynamics vary significantly. With 13.35 inches compressed length and 22.55 inches extended length, this shock delivers a 9.2-inch stroke—ideal for mid-range suspension travel in both street and competition applications. The steel construction with zinc plating provides corrosion resistance in wet environments while maintaining structural integrity under sustained stress. At 4.8 pounds, the monotube design minimizes internal friction and heat buildup during extended use, translating to more consistent damping response throughout the suspension cycle.

This rear shock is specified for builders upgrading existing suspension systems where OEM dampers no longer meet performance requirements—whether for drag racing, autocross, desert running, or street-driven modified vehicles. The monotube design excels in applications where space constraints exist or where conventional twin-tube shocks introduce fade during repeated cycling. QA1's valving approach allows end-users to dial in ride quality without requiring shock replacement, reducing long-term suspension optimization costs.

QA1 Shock monotube shocks have established themselves in the performance automotive market as reliable components for suspension development, valued for their manufacturing precision and responsive tuning capability. The 27 Series platform accommodates a broad range of vehicle weights and spring rates, making this shock applicable across multiple suspension architectures when paired with compatible mounting hardware.
