Key Features

• Up to 25% more damping performance than original equipment shocks
• Monotube design separates gas and oil for fade-free operation and fast response
• Higher gas pressure improves steering response
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Valving and components are tuned for GM truck applications
• Dust cover included

Product Details

The Gas-a-Just line is KYB’s monotube shock absorber series for drivers who want firmer control without giving up normal-road comfort. Part number KG5481 uses two working chambers: an air-free hydraulic section for damping response and a high-pressure nitrogen gas section with a floating piston for consistent performance. On Chevrolet K30, Chevrolet V30, Chevrolet V3500, GMC K3500, and GMC V3500 front suspension applications, that design helps maintain control under load and during repeated suspension movement.

This part cross-references Monroe Shocks & Struts 911190 for the same application.

What It Helps Address

• Excessive front-end bounce after bumps or dips
• Reduced steering response on heavy-duty trucks
• Shock fade during towing or hauling
• Suspension instability with larger, heavier tires and wheels
• Fluid leakage related to seal wear
