KYB Gas-A-Just Rear Monotube Shock Absorber KG5517 for Select 1952-1999 Ford, Mercury, and Chevy

Fits select 1952-1999 Ford, Mercury, Chevrolet, GMC, Volvo, Saab, and other domestic and import models. This KYB Gas-A-Just (MPN: KG5517) is a high-pressure monotube shock absorber designed to provide significantly more control and handling than standard twin-tube designs. It serves as a performance upgrade that automatically adjusts to road conditions, providing the damping force needed without the fade associated with fluid aeration.

The monotube configuration features two separate working chambers: a hydraulic piston and valve area for precise responsiveness, and a high-pressure nitrogen gas area with a floating piston. This design eliminates foaming and ensures the shock remains consistent even during high-demand driving or when supporting heavy motorhome chassis loads. By maintaining constant tire-to-road contact, these shocks help ensure that electronic safety systems and braking components operate as intended.

• Monotube design provides instant, automatic adjustment to driving conditions
• High-pressure nitrogen gas charge prevents oil foaming and shock fade
• Dual-chamber design with floating piston separates gas and hydraulic fluid for consistent damping
• Durable construction built to restore OE performance and stability
• Manufacturer Part Number: KG5517
