Product Description

The KYB KG5517 Gas-A-Just rear shock is a versatile monotube replacement ideal for classic Ford RWD vehicles (like Fairlane, Falcon, Mustang), Edsel models, motorhome chassis, and compact trucks such as the Daihatsu Rocky. Its high-pressure nitrogen design and velocity-sensitive valving provide up to 25% more damping control and fade resistance compared to standard twin-tube shocks.

Built with a seamless steel body, triple-chrome rod, and S-1 eyelet mounts, the KG5517 offers a direct bolt-in replacement for stock or heavy-duty springs--no custom work required. Sold individually to match your axle needs, this shock brings modern performance upgrades to vintage suspension setups while maintaining OEM-like ride quality and reliability. Ideal for classic restoration, towing applications, or upgraded suspension systems.
