KYB KG54332 Shock Absorber - Rear

KYB Gas-a-just Rear Shock for Ford Super Duty

The KYB Gas-a-just KG54332 is a monotube suspension shock absorber built for rear applications on select Ford Super Duty trucks. It uses separate gas and oil chambers for quick response, consistent damping, and reduced fade during demanding driving.

Key Features

• Monotube design separates gas and oil for fade-resistant operation and immediate response
• Up to 25% more damping performance than original equipment shocks
• Higher gas pressure improves steering response and suspension control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Valving and components are tuned specifically for Ford trucks
• Dust cover included
• Fits rear suspension applications on 1999-2004 Ford F-250 Super Duty and 1999-2004 Ford F-350 Super Duty

Product Details

Gas-a-just is KYB’s high-pressure monotube shock line, engineered for trucks that work, tow, or run larger wheels and tires. The KG54332 uses an air-free hydraulic working area for control and a separate high-pressure nitrogen chamber with a floating piston to maintain ride comfort during normal driving while adding damping on demand. This part cross-references Monroe Shocks & Struts (e.g., 911194) for the same application. For shoppers searching for a rear shock absorber for a 1999-2004 Ford F-250 Super Duty or rear shock for a 1999-2004 Ford F-350 Super Duty, KG54332 is a direct-fit option to review.

What It Helps Address

• Excessive rear-end bounce over bumps and uneven pavement
• Reduced control when towing or carrying heavier loads
• Shock fade from heat and aeration during extended use
• Delayed suspension response in trucks with larger tires and wheels
• Seal wear that can contribute to fluid leakage

Installation Notes

Verify compressed length, extended length, and mount style before installation: compressed length 16.93 in., extended length 27.87 in., stroke length 10.94 in., lower mount E2(12X38), upper mount E1. This rear shock absorber is listed for 1999-2004 Ford F-250 Super Duty and 1999-2004 Ford F-350 Super Duty. Confirm vehicle year, model, and rear position against the fitment data before ordering. Part number KG54332 should be matched to the application exactly.

Quality Assurance

KYB designs the Gas-a-just line with monotube construction and high-pressure gas separation to maintain consistent damping performance. The KG54332 is built to support the suspension behavior expected by the vehicle manufacturer, including systems that rely on stable braking, steering, and tire contact.
