Restore the ride and control of your full-size Ford with the KYB Gas-a-just High Pressure Monotube Gas Strut 551600, a front suspension strut built as an OE monotube replacement. It's a direct-fit front strut for the 2003-2011 Ford Crown Victoria, 2003-2011 Lincoln Town Car, and 2003-2011 Mercury Grand Marquis — see the Buyer's Guide tab for engine-level details.
The Gas-a-just monotube uses two separate working chambers: an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen gas chamber with a floating piston for a comfortable ride during normal driving and added performance on demand.
- Monotube design: separates the gas and oil for fade-free operation and instant response.
- Built to work: designed for vehicles that work, tow, and run larger, heavier tires and wheels.
- Triple chrome-plated piston rod: an ultra-smooth rod helps reduce seal wear, since fluid leaking can be a cause of strut failure.
- Quicker steering response: higher gas pressure helps improve steering response and supports Electronic Safety Systems performing as designed.
KYB recommends installing new strut mounts (part number SM5392) to reduce the chance of noise and vibration.
