KYB KG5417 Shock Absorber - Rear

KYB Gas-a-Just Rear Shock Absorber KG5417

The KYB Gas-a-Just KG5417 is a monotube rear shock absorber built as an OE-style replacement for GM vans and trucks that need firmer control and consistent damping. It uses separate hydraulic and gas chambers to deliver responsive handling on demand while maintaining a controlled ride in normal driving.

Key Features

• Monotube design with separate gas and oil chambers for fade-resistant operation and quick response
• Up to 25% more damping performance than original equipment shocks
• High-pressure nitrogen gas helps improve steering response and suspension control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Valving and components are tuned for GM truck applications
• Dust cover included
• Lower mount type: E2 (12.8 x 35); upper mount type: E2 (12.8 x 35)

Product Details

Gas-a-Just is KYB’s monotube shock line for drivers who want OE replacement fit and added damping authority. The KG5417 is designed for rear suspension use on Chevrolet and GMC vans, Blazer, Suburban, and Jimmy applications listed below. It is a strong match for vehicles that work, tow, or run larger wheels and tires, where added control can help maintain stable ride quality. This part cross-references Monroe Shocks & Struts (e.g., 34822) for the same application.

What It Helps Address

• Excessive rear bounce after bumps or load changes
• Reduced steering response and loose-feeling handling
• Shock fade during repeated suspension movement
• Seal wear that can lead to fluid leakage
• Loss of control on GM trucks and vans with heavier tire and wheel setups
