Product Information

Description:

Get the KYB KG4509 Shock Absorber for your vehicle. Buy now and secure your purchase online!

The Gas-a-just monotube shock absorber is available as an OE monotube replacement to restore your vehicles original capabilities. The KYB Gas-a-just has two separate working chambers: An air-free hydraulic piston and valve area for responsiveness and control, and a second high-pressure nitrogen gas area with a floating piston that provides a comfortable ride during normal driving and adds instant performance on demand.

Features and Benefits:

  • Adds up to 25% more damping performance over original equipment shocks
  • Components and valving designed specifically for classic Mopars
  • Electronic safety systems depend on the suspension, brakes and tires operating as the vehicle manufacturer intended. The KYB Gas-a-just helps keep Electronic Safety Systems performing as designed.
  • Fluid leaking can be a cause of shock failure, the KYB Gas-a-just has an ultra-smooth triple chrome plated chrome piston rod to reduce seal wear
  • Gas-a-Just monotubes include additional damping over OE design for vehicles that work, tow, and have larger, heavier tires & wheels
  • High pressure monotube design separates the gas and oil for fade free operation and instant response
  • The higher gas pressure of the KYB Gas-a-Just responds quickly to improve steering response
