The KYB Gas-a-Just has two separate working chambers: An air-free hydraulic piston and valve area for responsiveness and control, and a second high-pressure nitrogen gas area with a floating piston that provides a comfortable ride during normal driving and adds instant performance on demand. The Gas-a-Justs high-pressure, monotube design delivers the control spirited drivers are looking for and its ideal for European cars.
