KYB Gas-a-Just Monotube Front Shock Absorber KG4513

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.

The KYB Gas-a-Just KG4513 monotube shock absorber is designed to provide responsive handling, improved suspension control, and consistent performance for compatible vehicles. Its monotube construction separates the hydraulic working chamber from the high-pressure nitrogen gas chamber, helping the shock absorber react quickly to changing road and driving conditions.

A floating piston keeps the nitrogen gas separated from the hydraulic fluid, reducing aeration and helping prevent performance fade during demanding driving. The KYB Gas-a-Just automatically adjusts its damping response as suspension demands change, providing a controlled ride during normal driving with additional control available when cornering, braking, or carrying heavier loads. This design also supports proper suspension operation for vehicles equipped with electronic safety systems, including systems that rely on predictable braking, tire, and suspension performance.
