Firm up the ride and restore rear damping control with the KYB Gas-a-just Suspension Shock Absorber KG5508, a high-pressure monotube gas shock that installs as a direct-fit rear replacement for the 1965-1970 Buick Electra and LeSabre, 1971-1976 Cadillac Calais and DeVille, 1965-1968 Oldsmobile 98, 1967-1968 Oldsmobile Delmont 88, and 1965-1968 Oldsmobile Delta 88 — see the Buyer's Guide tab for engine details.

The Gas-a-just is offered as an OE monotube replacement to help restore your vehicle's original capabilities, with components and valving designed specifically for classic GM cars.

  • Twin-chamber monotube design: an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen gas chamber with a floating piston that separates gas and oil for fade-free operation and instant response.
  • Added damping: adds up to 25% more damping performance over original equipment shocks, with extra damping for vehicles that work, tow, and run larger, heavier tires and wheels.
  • Durable rod: an ultra-smooth triple chrome plated piston rod reduces seal wear, since fluid leaking can be a cause of shock failure.
  • Quick response: higher gas pressure responds quickly to improve steering response and helps keep Electronic Safety Systems performing as designed.

Is this a monotube or twin-tube shock?

It's a high-pressure monotube gas shock. The design separates the gas and oil, which helps provide fade-free operation and instant response.

How much damping does the Gas-a-just add?

KYB states it adds up to 25% more damping performance over original equipment shocks, with additional damping for vehicles that work, tow, or run larger, heavier tires and wheels.

What are signs my rear shocks may need replacing?

Common signs include excessive bouncing, a floaty or unstable ride, bottoming out over bumps, uneven tire wear, or visible fluid leaking from the shock body.

Should I replace shocks in pairs?

This listing is for one shock. Replacing the rear shocks as a pair is recommended for balanced, even damping across the axle.
