KYB Shocks & Struts Gas-A-Just

The KYB Gas-a-just monotube shock absorber has additional performance advantages over the traditional twin-tube design: It can instantly, automatically adjust to your performance needs and never experiences fade due to aeration. 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. Electronic safety systems depend on the suspension, brakes and tires operating as the vehicle manufacturer intended. The KYB Gas-a-just helps keep Electronic Safety Systems performing as designed.
