KYB KG5498 Shock Absorber - Rear

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

The KYB Gas-a-Just KG5498 is a monotube suspension shock absorber built for rear applications on Ford E-Series vans and wagons. It is engineered to deliver firmer control than a conventional twin-tube design while maintaining a composed ride during normal driving.

For Ford E-150, E-250, and E-350 Super Duty rear suspension service, this Gas-a-Just shock uses separate gas and oil chambers for quick response and fade-resistant damping. The KG5498 is a direct-fit performance upgrade for vehicles that work hard, tow, or run larger tires and wheels.

Key Features

• Monotube design with separate gas and oil chambers for consistent damping response
• Up to 25% more damping performance than original equipment shocks
• High-pressure nitrogen gas helps reduce fade from aeration
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Designed specifically for Ford vans and rear suspension applications
• Improves steering response and suspension control under load
• Dust cover included

Product Details

KYB Gas-a-Just shocks are built around a high-pressure monotube layout that keeps the hydraulic working area and gas charge separated. That design supports faster reaction to road inputs and more stable damping when the suspension is working harder. The KG5498 measures 13.39 inches compressed, 21.65 inches extended, and provides 8.27 inches of stroke, with lower mount type E2(12X38) and upper mount type S1.

This part cross-references Monroe Shocks & Struts 34761 for the same application. It is also associated with Ford service numbers used across E-Series rear shock applications, including KG5498 replacement searches for Ford E-150, Ford E-250, and Ford E-350 Super Duty.

What It Helps Address

• Excessive rear bounce or oscillation over uneven pavement
• Reduced control when carrying cargo or towing
• Shock fade from heat and aeration during repeated suspension movement
• Loose steering feel caused by worn rear damping on van platforms
• Ride instability on Ford E-Series vehicles with heavier tires and wheels
