Frequently Asked Questions
What is the difference between a monotube and a twin-tube design?
Twin-tube design shocks and struts have two cylinders; one inside of the other. The inner working cylinder is where the shaft and piston move up and down in hydraulic fluid. The outer cylinder serves as a reservoir for the hydraulic fluid. The twin tube has fluid valves in both the piston as well as at the base of the working cylinder. This design is efficient for most vehicles being used within their designed operation. A monotube shock is designed with a single cylinder and two pistons. One piston is attached to the shaft and contains valves to control the flow of fluid. The second piston is a floating piston located near the bottom of the cylinder. The floating piston separates the hydraulic fluid from a pressurized nitrogen gas chamber that both cushions and adds response to any aggressive vehicle movement. This design is more responsive and will add more handling & control over the twin tube design.
