KYB KG54310 Shock Absorber - Rear

KYB Gas-a-just Rear Shock for Ford Windstar

The KYB Gas-a-just KG54310 is a rear suspension shock absorber built for 1995-2003 Ford Windstar models with no rear air spring. It uses a monotube design that separates gas and oil for consistent damping response and reduced fade during demanding driving.

Gas-a-just Performance Line

KYB Gas-a-just shocks are tuned for vehicles that carry extra load, tow, or run larger wheels and tires. This line adds damping performance over OE-style twin-tube designs while maintaining a controlled ride during normal driving. For the Ford Windstar, the valving and components are matched to the application for rear suspension control.

Detailed Description

The KYB Gas-a-just KG54310 is a rear suspension shock absorber for the Ford Windstar, designed for 1995-2003 models without rear air spring. Its monotube layout uses an air-free hydraulic working area for control and a high-pressure gas chamber with a floating piston for immediate damping response. This design supports stable handling, improved steering response, and consistent performance under load. The KG54310 part number is also referenced by Monroe Shocks & Struts 37110 and Gabriel G63676 for the same application.

What This Shock Helps Address

• Excessive rear bounce after bumps or dips
• Reduced control when carrying passengers or cargo
• Shock fade from heat and aeration during extended driving
• Loose or delayed steering response caused by worn rear damping
• Uneven ride quality from aging rear suspension components

Installation Notes and Tips

Verify rear fitment on 1995-2003 Ford Windstar models with no rear air spring before ordering. Match the mount style and compressed/extended length to the original shock location: compressed length 10.47 in., extended length 15.35 in., stroke length 4.88 in. Inspect surrounding suspension bushings and mounting points during replacement, and confirm the rear shock is installed in the correct position.

Quality Assurance

KYB designs Gas-a-just shocks with application-specific valving and a high-pressure monotube layout to maintain consistent damping performance. The KG54310 uses a triple chrome plated piston rod to help reduce seal wear and support long-term operation in the rear suspension of the Ford Windstar.
