Upgrade your classic Mopar's ride with the KYB Gas-a-just Suspension Shock Absorber KG4509, a high-pressure monotube gas KYB shock absorber for the FRONT position. It fits the 1960-1976 Plymouth Valiant, 1962-1976 Dodge Dart, 1964-1969 Plymouth Barracuda, 1970-1976 Plymouth Duster, and 1971-1976 Plymouth Scamp — see the Buyer's Guide tab for engine-level details.

  • Monotube gas design: Available as an OE monotube replacement intended to restore your vehicle's original capabilities, with an air-free hydraulic piston and valve area for responsiveness plus a high-pressure nitrogen gas chamber and floating piston for a comfortable ride and instant response.
  • Extra damping: Adds up to 25% more damping performance over original-equipment shocks, with components and valving designed specifically for classic Mopars.
  • Fade-free operation: The high-pressure monotube separates the gas and oil for fade-free operation, and the higher gas pressure responds quickly to help improve steering response.
  • Durable rod: An ultra-smooth triple-chrome-plated piston rod is designed to reduce seal wear, since fluid leaking can be a cause of shock failure.

KYB notes the Gas-a-just also helps keep Electronic Safety Systems performing as designed. For balanced handling, replace the front shocks as a matched pair.
