KYB KG5440 Shock Absorber - Front

KYB Gas-a-Just Front Shock Absorber KG5440

The KYB Gas-a-Just KG5440 is a front monotube shock absorber built for trucks and SUVs that need firmer control than a standard twin-tube design. It is a direct-fit suspension shock absorber for select Dodge Dakota, Dodge Durango, Ford F-150, Ford F-250, Ford F-350, Ford Bronco, Ford Bronco II, Ford Ranger, and Ford F-100 applications.

Key Features

• Up to 25% more damping performance than original equipment shocks
• Monotube construction separates gas and oil for consistent response and fade-resistant operation
• High-pressure nitrogen gas helps the shock react quickly to steering and road inputs
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Valving and components are tuned for domestic truck applications
• Designed for vehicles that work, tow, or run larger, heavier tires and wheels
• Dust cover included

Product Details

Gas-a-Just is KYB’s performance-oriented shock line for drivers who want more control without sacrificing everyday ride quality. The KG5440 uses a monotube design with separate working chambers: one for hydraulic response and one for high-pressure nitrogen gas. That layout helps maintain damping consistency under load, improves steering response, and reduces fade during repeated suspension movement. For front suspension service on a Ford F-150 front shock replacement, a Dodge Dakota front shock upgrade, or a Ford Bronco front monotube performance upgrade, the KG5440 is built to deliver controlled handling and stable ride behavior.

This part cross-references Monroe Shocks & Struts 911220 for the same application.

Common Problems This Shock Can Address

• Excessive front-end bounce over bumps and rough pavement
• Reduced steering response during braking or lane changes
• Shock fade during towing, hauling, or repeated suspension compression
• Premature seal wear related to fluid leakage
• Loss of control feel on trucks with heavier tires and wheels

Quality Assurance
