Description

Part #: 5510021

The Gas-a-just monotube strut is available as an OE monotube replacement to restore your vehicle's original capabilities. 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.

MIA's Description

The KYB Gas-A-Just shock absorber enhances vehicle stability, handling, and control through its monotube design. This design makes the shock absorber more responsive to road conditions and allows it to automatically adjust to driving demands. The Gas-A-Just strut offers a slightly firmer ride, providing additional control by limiting body roll and nose dive.
