KYB KG5442 Shock Absorber - Rear

KYB Gas-a-just Rear Shock for Ford Trucks

The KYB Gas-a-just KG5442 is a rear monotube shock absorber built for Ford truck and SUV applications that need firmer control than a standard twin-tube design. It is a direct-fit suspension shock absorber for select Ford F-350, Bronco, F-100, and F-150 models, with valving tuned for heavier-duty use.

Gas-a-just Product Line

KYB Gas-a-just shocks use a high-pressure monotube design with separate gas and oil chambers. That layout helps maintain consistent damping, reduces fade from aeration, and delivers quicker response when load, towing, or larger wheels and tires increase suspension demand.

Key Features

• Part number KG5442
• Rear suspension shock absorber for select Ford applications
• Up to 25% more damping performance over original equipment shocks
• Monotube construction for fade-free operation and instant response
• High-pressure nitrogen gas and hydraulic working chambers for control and ride comfort
• Triple chrome plated piston rod helps reduce seal wear
• Dust cover included
• Designed for Ford trucks that work, tow, or run larger, heavier tires and wheels

Detailed Description

KYB KG5442 is engineered for rear suspension use on 1980-1997 Ford F-350, 1980-1983 Ford Bronco, 1980-1983 Ford F-100, and 1980-1983 Ford F-150. This shock absorber uses a monotube layout with an air-free hydraulic piston area for responsiveness and a separate high-pressure gas chamber for consistent damping under changing road and load conditions. The result is stable control during normal driving and stronger damping when the vehicle is carrying weight or working harder. This part cross-references Monroe Shocks & Struts (e.g., 34797) for the same application.

What It Helps Address

• Excessive rear bounce after bumps or dips
• Reduced control when towing or hauling
• Shock fade from heat and aeration during extended use
• Loose steering feel caused by worn rear damping on truck applications
• Uneven ride quality on Ford trucks with heavier tires and wheels
