KYB KG5496 Shock Absorber - Rear

KYB Gas-a-Just Rear Shock for Ford E-150

The KYB Gas-a-Just KG5496 is a rear suspension shock absorber built for Ford E-150 vans that need firmer control and consistent damping. It uses a monotube design with separate gas and oil chambers to deliver quick response, reduced fade, and stable ride control during everyday driving and heavier-duty use.

Key Features

• Up to 25% more damping performance than original equipment shocks
• Monotube construction separates gas and oil for fade-free 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 engineered specifically for Ford vans
• 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 than a standard twin-tube design can provide. The KG5496 uses an air-free hydraulic working area for responsiveness and a separate high-pressure nitrogen chamber for added support when load, road conditions, or driving demands increase. This makes it a strong choice for Ford E-150 and Ford E-150 Econoline rear suspension service where ride stability and steering response matter. This part cross-references Monroe Shocks & Struts 911080 for the same application.

Common Problems This Shock Can Address

• Excessive rear bounce or oscillation over bumps
• Reduced control when carrying cargo or towing
• Soft or delayed suspension response on worn OE shocks
• Shock fade from heat and aeration during repeated use
• Fluid leakage related to seal wear on aging dampers

Quality Assurance

KYB designs Gas-a-Just shocks to maintain consistent damping performance and support the suspension behavior the vehicle manufacturer intended. The monotube layout, high-pressure gas charge, and chrome piston rod are used to improve response and reduce wear in demanding rear suspension applications.
