KYB Gas-a-Just Monotube Shock Absorber KG4550 for Volvo 164 and 145

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 monotube shock absorber is designed to provide responsive handling, consistent control, and improved suspension performance for applicable vehicles. Unlike a traditional twin-tube shock, its monotube design uses separate working chambers to maintain pressure and control under changing driving conditions.

An air-free hydraulic piston and valve area delivers responsive damping, while a high-pressure nitrogen chamber with a floating piston helps reduce aeration and shock fade. The result is a comfortable ride during normal driving with additional performance available when cornering, braking, or encountering uneven road surfaces. The KYB Gas-a-Just is engineered to support the suspension performance expected by the vehicle manufacturer.

Electronic safety systems depend on the suspension, brakes, and tires operating as intended. By helping maintain controlled suspension movement, the KYB Gas-a-Just supports the proper operation of electronic safety systems. This automotive shock absorber is identified by KYB part number KG4550 and is intended for front and rear applications on select classic Volvo models.

Fitment: Fits 1970–1974 Volvo 145 and 1970–1974 Volvo 164 applications. Verify the vehicle configuration and application position before ordering.
