KYB KG5480 Shock Absorber - Front

KYB Gas-a-Just Front Shock Absorber KG5480

The KYB Gas-a-just KG5480 is a front suspension shock absorber built for GM trucks and SUVs that need firmer control without giving up everyday ride quality. Its monotube design separates gas and oil for quick response and consistent damping, making it a practical choice for Chevrolet Astro, GMC Safari, Tahoe, Yukon, and K1500/K2500/K3500 applications.

Key Features

• Up to 25% more damping performance than original equipment shocks
• Monotube construction with separate gas and oil chambers for fade-resistant operation
• High-pressure nitrogen gas helps deliver immediate response and improved steering feel
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage risk
• Dust cover included for added protection
• Valving and components are tuned for GM truck and SUV suspension demands
• Part number KG5480 for front suspension service

Product Details

Gas-a-just is KYB’s performance-oriented shock line for vehicles that work harder than a typical commuter. The monotube design uses an air-free hydraulic working area for control and a separate high-pressure gas chamber for consistent force delivery. That layout helps the KG5480 respond quickly during braking, cornering, towing, and load changes, while maintaining stable damping on Chevrolet K1500, K2500, and K3500 front suspension setups as well as GMC K-series and full-size SUV applications. This part cross-references Monroe Shocks & Struts 911511 for the same application.

What It Helps Address

• Excessive front-end bounce over bumps and uneven pavement
• Reduced steering response during load transfer or towing
• Shock fade caused by aeration in conventional twin-tube designs
• Premature seal wear related to piston rod surface condition
• Loss of control feel on GM trucks and SUVs with heavier tires and wheels
