Gas-a-Just Rear Shock Absorber

The KYB Gas-a-Just 555601 is a rear shock absorber engineered to upgrade the performance and handling of compatible Ford Crown Victoria, Lincoln Town Car, and Mercury Grand Marquis models. Constructed with a high-pressure nitrogen gas design within a monotube configuration, these shocks eliminate aeration, leading to quicker response times and consistent performance. The increased damping force automatically adjusts to road conditions, offering precise control and stability, especially during demanding driving situations. The durable seamless working cylinder is manufactured from a single piece of steel to minimize leak potential, and a triple-chrome plated piston rod ensures strength and resistance to corrosion for extended lifespan. These shocks are built with heavy-duty construction, making them suitable for both performance and utility applications. Specifications for the KYB Gas-a-Just 555601 include a compressed length of 12.92 inches and an extended length of 20.09 inches, with a stroke length of 7.17 inches. The lower mount type is E2(12.2X67.5) and the upper mount type is S1.
