Dial in confident, fade-free damping for your classic GM ride with the KYB Gas-a-just shock absorber (P/N KG5508), a high-pressure monotube gas shock built as a rear-position, OE monotube replacement to help restore your vehicle's original ride and handling. This KYB shock absorber is a direct-fit replacement for the 1965-1970 Buick Electra and LeSabre, 1971-1976 Cadillac Calais and DeVille, 1965-1968 Oldsmobile 98 and Delta 88, and the 1967-1968 Oldsmobile Delmont 88.

The 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 quick response.
  • More damping: Adds up to 25% more damping than original equipment shocks, with components and valving designed specifically for classic GM cars.
  • Built to work: Extra damping over the OE design suits vehicles that work, tow, or run larger, heavier tires and wheels.
  • Smooth rod: Triple chrome-plated piston rod reduces seal wear; higher gas pressure improves steering response.

It also helps keep Electronic Safety Systems performing as designed.
