Get controlled, comfortable damping from the KYB shock absorber Gas-a-just KG54317, a high-pressure monotube gas unit that installs as a rear shock on the 1996-2002 Toyota 4Runner. Its components and valving were designed specifically for the Toyota 4Runner, making it a direct-fit rear replacement for the listed applications.

The Gas-a-just is offered as an OE monotube replacement to help restore your vehicle's original capabilities. It uses two separate working chambers: an air-free hydraulic piston and valve area for responsiveness and control, and a high-pressure nitrogen gas area with a floating piston for a comfortable ride during normal driving with added performance on demand.

  • Up to 25% more damping: adds damping over original-equipment shocks, with extra capacity for vehicles that work, tow, or run larger, heavier tires and wheels.
  • Triple chrome-plated piston rod: an ultra-smooth rod helps reduce seal wear, since fluid leaking can be a cause of shock failure.
  • Higher gas pressure: responds quickly to help improve steering response.
  • Monotube design: separates the gas and oil for fade-free operation and instant response, and helps keep Electronic Safety Systems performing as designed.

Shocks work as a pair — replace both rear units together for balanced, even damping.
