KYB 553392 Shock Absorber - Rear

KYB Gas-a-just Rear Shock Absorber

KYB Gas-a-just 553392 is a monotube rear shock absorber built as an OE-style replacement to restore original ride control. It uses separate hydraulic and high-pressure gas chambers for quick response, stable damping, and consistent performance in daily driving and heavier-duty use.

Key Features

• Monotube OEM replacement for direct suspension service
• Separate gas and oil chambers for fade-resistant operation
• High-pressure nitrogen design for faster steering response and control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Built for vehicles that tow, work, or run larger tires and wheels
• Supports proper suspension behavior for electronic safety systems
• Rear application for Ford Escape and Lincoln MKC fitments

Product Details

The KYB Gas-a-just line is engineered for drivers who want OE monotube replacement performance with firmer control than a conventional twin-tube design. Part number 553392 uses an air-free hydraulic working area and a separate nitrogen gas chamber with a floating piston, helping the shock react quickly to road inputs while maintaining consistent damping. This design is well suited to the Ford Escape rear shock absorber application and the Lincoln MKC rear shock absorber application listed here.

This part cross-references Ford CV6Z18125E and CV6Z18125M for the same application.

What It Helps Address

• Excessive rear bounce after bumps
• Loose or delayed steering response
• Reduced control when towing or carrying added load
• Shock fade during repeated suspension movement
• Ride instability from worn rear dampers
