KYB KG54313 Suspension Shock Absorber - Front

KYB Gas-a-just Front Shock for Ford Trucks

The KYB Gas-a-just KG54313 is a front monotube shock absorber built for Ford truck and SUV applications that need firmer control than a standard twin-tube design. It uses separate gas and oil chambers for quick response, consistent damping, and reduced fade during demanding driving.

For Ford F-150, Ford Expedition, and Ford F-250 front suspension service, this KYB Gas-a-just shock is tuned to add control for towing, hauling, and vehicles running larger tires and wheels. The KG54313 is a direct-fit suspension shock absorber for the listed front applications.

Key Features

• Monotube design separates gas and oil for fade-resistant operation and fast response
• Adds up to 25% more damping performance over original equipment shocks
• Valving and components are engineered specifically for Ford truck applications
• Higher gas pressure improves steering response and suspension control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Dust cover included for added protection
• R-stop design for controlled rebound behavior

Product Details

The KYB Gas-a-just line is designed for drivers who want more suspension control without giving up everyday ride quality. This monotube shock absorber uses an air-free hydraulic working area for responsiveness and a high-pressure nitrogen chamber with a floating piston to maintain consistent performance as road conditions change. The KG54313 measures 9.57 inches compressed, 14.06 inches extended, and 4.49 inches of stroke, with lower mount type E2(12.8X40) and upper mount type S1.

This part cross-references Monroe Shocks & Struts 911133 and Gabriel 77716 for the same application. It is a strong fit for front suspension service on 1997-2003 Ford F-150, 1997-2002 Ford Expedition, 1997-1999 Ford F-250, and 2004 Ford F-150 Heritage front applications listed below.

What It Helps Address

• Excessive front-end bounce over rough pavement
• Reduced steering response from worn shocks
• Shock fade during towing or hauling
• Instability with heavier tires and wheels
• Loss of damping control from aging OE shocks
