KYB Suspension Shock Absorber P/N:551136

Meet the KYB Gas-a-just High Pressure Monotube Gas Shock (P/N 551136), a rear KYB shock absorber built to restore your vehicle's original ride control. It drops in as an OE monotube replacement for the 2011-2023 Chrysler 300, 2011-2023 Dodge Challenger, and 2011-2023 Dodge Charger — see the Buyer's Guide tab to confirm your engine and trim. The Gas-a-just runs two separate 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.

• High-pressure monotube design: separates the gas and oil for fade-free operation and instant response.
• Triple chrome-plated piston rod: since fluid leaking can be a cause of shock failure, this ultra-smooth rod reduces seal wear.
• Quick-responding gas pressure: the higher gas pressure helps improve steering response and helps keep Electronic Safety Systems performing as designed.
• Made to work: Gas-a-just monotubes are designed for vehicles that work, tow, and run larger, heavier tires and wheels.

This KYB gas shock absorber helps restore the designed control and handling of the 2011-2023 Chrysler 300. To reduce the chance of noise and vibration, KYB recommends installing new strut mounts, part number SM5533.
