Firm up ride control on your classic GM with the KYB Gas-a-just Suspension Shock Absorber KG5506, a high-pressure monotube gas shock. It installs as a direct-fit rear shock for the 1974-1975 Buick Apollo, 1975-1979 Buick Skylark, 1976-1979 Cadillac Seville, 1968 Chevrolet Chevy II, 1969-1979 Chevrolet Nova, 1974-1979 Oldsmobile Omega, 1977-1979 Pontiac Phoenix, and 1974-1977 Pontiac Ventura — see the Buyer's Guide tab for engine-level detail.

KYB's Gas-a-just monotube uses two separate working chambers: an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen gas area with a floating piston for a comfortable ride during normal driving and added performance on demand.

  • Monotube design: separates the gas and oil for fade-free operation and instant response.
  • Added damping: adds up to 25% more damping performance over original-equipment shocks, with components and valving designed specifically for classic GM cars.
  • Triple chrome-plated piston rod: ultra-smooth rod helps reduce seal wear, since fluid leaking can be a cause of shock failure.
  • Steering response: the higher gas pressure responds quickly to help improve steering response and helps keep Electronic Safety Systems performing as designed.

Frequently Asked Questions

What is the KYB KG5506?

It's the KYB Gas-a-just Suspension Shock Absorber, a high-pressure monotube gas shock. The catalog lists it in the rear position for the covered classic GM applications.

What vehicles does this shock fit?

It fits the 1974-1975 Buick Apollo, 1975-1979 Buick Skylark, 1976-1979 Cadillac Seville, 1968 Chevy II, 1969-1979 Nova, 1974-1979 Olds Omega, 1977-1979 Pontiac Phoenix, and 1974-1977 Pontiac Ventura.

How does the monotube design help?

The high-pressure monotube separates the gas and oil for fade-free operation and instant response, and it never experiences fade due to aeration during normal driving.

What does the triple chrome-plated piston rod do?

The ultra-smooth triple chrome-plated rod is designed to reduce seal wear. Because fluid leaking can be a cause of shock failure, this helps protect the seal over time.

Should I replace both rear shocks together?

This listing is for one shock. Replacing both sides as a matched pair is recommended for balanced, even ride control; confirm the quantity your vehicle needs.
