KYB Gas-a-Just Rear Monotube Shock Absorber KG5512

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.

Brief Description: The KYB Gas-a-Just KG5512 rear monotube shock absorber is designed to provide responsive handling, improved control, and consistent performance for select classic Chrysler, Dodge, and Plymouth vehicles. Its monotube design automatically adjusts to changing driving conditions, delivering a comfortable ride during everyday use while providing additional damping performance when needed.

Performance and Design: The KYB Gas-a-Just uses two separate working chambers. An air-free hydraulic piston and valve area helps maintain responsive control, while a high-pressure nitrogen gas chamber with a floating piston helps prevent aeration and shock fade. This design allows the shock absorber to react quickly to changes in vehicle movement without sacrificing ride quality. Properly functioning suspension components also support the operation of electronic safety systems by helping the vehicle maintain the handling characteristics intended by the manufacturer.
