Keep the rear suspension planted and controlled with the KYB shock absorber 554406, a high-pressure monotube gas unit that installs as a direct OE monotube replacement in the rear position on the 2013-2018 Acura RDX. This KYB Gas-a-just is engineered to help restore the designed control and handling of the 2013-2018 Acura RDX.

  • High-pressure monotube design: separates the gas and oil for fade-free operation and instant response.
  • Two 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.
  • Triple chrome-plated piston rod: an ultra-smooth surface that reduces seal wear, since fluid leaking can be a cause of shock failure.
  • Higher gas pressure: responds quickly to help improve steering response, and helps keep Electronic Safety Systems performing as designed.

As the correct monotube-designed OEM replacement, this KYB gas shock absorber is designed for vehicles that work, tow, and run larger, heavier tires and wheels. It fits the rear axle; replacing both rear shocks together as a matched pair is recommended for balanced, even handling.
