KYB KG5194 Shock Absorber - Rear

KYB Gas-a-Just Rear Shock for Hummer H2

The KYB Gas-a-Just KG5194 is a monotube suspension shock absorber built as an OE-style replacement for the rear of the 2003-2007 Hummer H2. It is designed to restore original handling characteristics while adding quick response for heavier-duty use, including towing and larger wheel and tire setups.

Key Features

• Monotube OE replacement shock absorber for rear suspension service
• Separate hydraulic and high-pressure nitrogen chambers for consistent damping response
• Built for vehicles that work, tow, and carry larger, heavier tires and wheels
• High-pressure design helps reduce fade and improve steering response
• Triple chrome plated piston rod helps reduce seal wear from fluid leakage
• Dust cover included
• Lower mount type: E2 (14.2 x 43); upper mount type: E2 (14.2 x 43)

Detailed Description

KYB Gas-a-Just KG5194 is engineered to replace the original rear shock on the Hummer H2 with a monotube design that separates gas and oil for fast response and stable control. The air-free hydraulic working area supports precise damping, while the high-pressure nitrogen chamber with floating piston helps maintain ride comfort during normal driving and adds immediate performance when suspension demand increases. This makes the KYB Gas-a-Just KG5194 a practical choice for Hummer H2 rear shock replacement when the vehicle is used for towing, hauling, or fitted with heavier wheels and tires. This part cross-references Monroe Shocks & Struts (e.g., 911508) for the same application.

Common Problems It Can Address

• Excessive bounce or poor rear suspension control
• Reduced steering response after shock wear
• Fluid leakage from worn shock seals
• Fade during repeated load changes or towing
• Loss of original ride quality on a Hummer H2 rear suspension

Installation Notes and Tips

Fits 2003-2007 Hummer H2, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify mount style and compressed/extended length before installation. The KG5194 is a direct-fit rear shock absorber for the listed application, and the part number KG5194 should be matched to the vehicle’s rear suspension configuration before service.

Quality Assurance

KYB designs the Gas-a-Just line as an OE monotube replacement to help restore the vehicle’s intended suspension control and handling. The KG5194 uses a high-pressure monotube layout and a chrome-plated piston rod to support consistent operation in demanding rear suspension use.
