KYB KG5501 Shock Absorber - Rear

KYB Gas-a-just Rear Shock for Corvette

The KYB Gas-a-just KG5501 is a rear suspension shock absorber for 1963-1982 Chevrolet Corvette applications. Built as a monotube design, it delivers quick response, consistent damping, and control for street-driven Corvettes that see performance use.

Gas-a-just Product Line

KYB Gas-a-just shocks use separate gas and oil chambers to reduce fade and maintain response under load. The high-pressure nitrogen gas section supports firmer control when the suspension is working harder, while the hydraulic chamber helps preserve ride quality during normal driving.

Detailed Description

KYB KG5501 is engineered for the rear of the Chevrolet Corvette from 1963 through 1982. The Gas-a-just design separates gas and oil to maintain consistent damping and reduce aeration-related fade, which is important on vehicles that work harder, tow, or run larger wheels and tires. This shock absorber is built to add control without sacrificing everyday drivability, making it a direct-fit performance upgrade for Corvette owners looking to sharpen suspension response.

This part cross-references Monroe Shocks & Struts 5850 for the same application.

What It Helps Address

• Excessive rear-end bounce after bumps
• Reduced damping control from worn OE shocks
• Suspension fade during repeated load changes
• Slow steering response tied to weak shock control
• Uneven ride quality on a performance-oriented Corvette
