KYB KG5479 Shock Absorber - Rear

KYB Gas-a-just Rear Shock for GM Trucks

The KYB Gas-a-just KG5479 is a rear monotube shock absorber built for GM trucks and SUVs that need firmer control and consistent damping. It is designed for vehicles such as the Chevrolet C1500, K1500, Tahoe, and GMC Yukon, with performance-focused valving for towing, hauling, and larger wheel and tire setups.

Gas-a-just Line Overview

KYB’s Gas-a-just line uses a monotube design with separate gas and oil chambers for quick response and fade-resistant operation. The higher gas pressure helps the shock react faster to steering and suspension movement, while the internal design supports a more controlled ride under load.

Key Features

• Monotube shock absorber with air-free hydraulic response and high-pressure nitrogen gas separation
• Up to 25% more damping performance than original equipment shocks
• Valving and components tuned for GM truck applications
• Fade-resistant operation for work, towing, and heavier tire and wheel packages
• Triple chrome plated piston rod helps reduce seal wear
• Dust cover included
• Rear position application
