KYB Suspension Shock Absorber P/N:KG5512

Firm up the rear of your classic Mopar with the KYB Gas-a-just Suspension Shock Absorber KG5512, a high-pressure monotube gas shock that installs in the rear position. It fits the listed applications including the 1965-1969 Chrysler 300, 1966-1976 Dodge Charger, 1970-1974 Dodge Challenger, 1970-1974 Plymouth Barracuda, and the 1970 Plymouth Superbird — see the Buyer's Guide tab for the full 35-vehicle list and engine details.

• Monotube gas design: The Gas-a-just uses an air-free hydraulic piston and valve area plus a separate high-pressure nitrogen gas chamber with a floating piston, so the gas and oil stay separated for fade-free operation 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 that work, tow, and run larger, heavier tires and wheels.
• Reduced seal wear: An ultra-smooth triple-chrome-plated piston rod helps reduce seal wear, since fluid leaking can be a cause of shock failure.
• Quicker response: Higher gas pressure responds quickly to help improve steering response and keeps electronic safety systems performing as designed.
