KYB KG5492 Shock Absorber - Rear

KYB Gas-a-just Rear Shock for Ford Aerostar

The KYB Gas-a-just KG5492 is a rear monotube shock absorber built for 1989-1997 Ford Aerostar models. It is engineered to deliver quicker response, firmer control, and fade-resistant damping for vehicles that work harder than a typical daily driver.

For Ford Aerostar rear suspension service, this KYB Gas-a-just shock absorber uses a high-pressure monotube design to separate gas and oil for consistent operation. The KG5492 is a direct-fit rear shock choice for Aerostar owners looking to restore control after wear, fluid leakage, or reduced damping performance.

Product Details

The KYB Gas-a-just line is built for drivers who want more control than a standard twin-tube shock can provide. On the Ford Aerostar, the KG5492 uses KYB’s monotube construction to improve steering response and maintain damping consistency when suspension demands increase. The air-free hydraulic working area supports precise control, while the high-pressure gas chamber helps the shock react quickly during normal driving and heavier use. This part number, KG5492, is a practical OE-style upgrade for rear suspension refresh work on the Ford Aerostar.

This part cross-references Monroe Shocks & Struts 37061 for the same application.

Common Problems This Shock Can Address

• Rear-end bounce or excessive body movement
• Reduced damping after shock fluid leakage
• Loose or delayed rear suspension response
• Loss of control when towing or carrying heavier loads
• Inconsistent ride quality on Aerostar rear suspension systems

Installation Notes

Compatible With 1989-1997 Ford Aerostar rear suspension applications. Verify compressed length, extended length, and mount type before installation: compressed length 11.93 in., extended length 17.44 in., stroke length 6.3 in., lower mount E2(12X38), upper mount E2(12X41).

Quality Assurance

KYB designs the Gas-a-just series with a monotube layout that separates gas and oil for fade-resistant performance and fast response. The KG5492 is built with a triple chrome plated piston rod to help reduce seal wear and support long-term shock function in rear Ford Aerostar service.
