Description

Deliver confident, fade-free damping to your classic ride with the KYB Gas-a-just Suspension Shock Absorber (KG4550). This high-pressure monotube gas shock is a direct-fit replacement for the 1965-1985 Avanti II; 1955-1964 Chevrolet Bel Air; 1958-1964 Chevrolet Biscayne; 1960-1964 Chevrolet Corvair; 1963-1982 Chevrolet Corvette; 1959-1964 Chevrolet Impala; 1958-1962 Pontiac Bonneville and Catalina; 1967-1974 Volvo 142 and 144; 1968-1974 Volvo 145; and 1969-1975 Volvo 164 — see the Buyer's Guide tab for the full list. Depending on the application, it serves the front or rear position.

Monotube gas design: separates the gas and oil for fade-free operation and instant response, avoiding the aeration fade of a traditional twin-tube.
Two working chambers: an air-free hydraulic piston/valve area for responsiveness and control, plus a high-pressure nitrogen gas area with a floating piston.
Triple chrome plated piston rod: ultra-smooth surface designed to reduce seal wear, since fluid leaking can be a cause of shock failure.
Adds up to 25% more damping over original equipment shocks, with components and valving designed specifically for classic cars.

The higher gas pressure is designed to help improve steering response and keep electronic safety systems performing as the vehicle manufacturer intended. Worn shocks may show up as excessive bounce, nose dive, or poor ride control.

Frequently Asked Questions

What is the KYB KG4550?

It's a KYB Gas-a-just high-pressure monotube gas shock absorber (MPN KG4550) that provides damping and ride control for the listed classic-car applications.

How is a monotube shock different from a twin-tube?

The Gas-a-just monotube separates the gas and oil into distinct chambers for fade-free operation and instant response, avoiding the aeration fade a twin-tube can experience.

Does this shock mount at the front or rear?

Depending on the application, it serves the front or rear position. Check the Buyer's Guide tab to confirm the correct location for your vehicle.

What does the triple chrome plated piston rod do?

Its ultra-smooth surface is designed to reduce seal wear. Since fluid leaking can be a cause of shock failure, this helps protect the seal over time.

What are signs my shocks may need replacing?

Excessive bouncing, nose dive under braking, poor ride control, or fluid leaking may indicate worn shocks. Diagnose the cause before replacing to confirm this is the issue.
