Settle the ride and sharpen response at the rear with the KYB Gas-a-just Shock Absorber 5540041, a high-pressure monotube gas shock. It installs as a direct-fit rear replacement for the 2003-2009 Toyota 4Runner and 2007-2009 Toyota FJ Cruiser — see the Buyer's Guide tab for engine-level fitment.

  • Monotube gas design: Two separate working chambers — an air-free hydraulic piston/valve area for responsiveness and control, plus a high-pressure nitrogen gas area with a floating piston for ride comfort and on-demand performance.
  • Fade-free operation: Separating the gas and oil helps prevent aeration for consistent damping and instant response.
  • Built to work: Gas-a-just monotubes are designed for vehicles that work, tow, and run larger, heavier tires and wheels; the higher gas pressure is designed to improve steering response.
  • Durable piston rod: An ultra-smooth triple chrome-plated piston rod helps reduce seal wear, since fluid leakage can be a cause of shock failure.

As the correct monotube-designed OE replacement, it helps restore the designed control and handling and helps keep Electronic Safety Systems performing as intended. Sold individually; replacing both rear shocks together is recommended for balanced ride control.

What vehicles does the KYB 5540041 fit?

It is a direct-fit rear shock for the 2003-2009 Toyota 4Runner and 2007-2009 Toyota FJ Cruiser. Check the Buyer's Guide tab to confirm the exact application for your vehicle.

Is this a front or rear shock?

This is a rear-position shock absorber for the listed applications.

What is a monotube gas shock?

It uses a single tube with separate gas and oil chambers divided by a floating piston. Separating gas and oil helps prevent aeration for fade-free, responsive damping.

Do I need to replace both rear shocks?

The 5540041 is sold individually. Replacing both rear shocks as a matched pair is recommended for balanced, even ride control.

What signs suggest my rear shocks may need replacing?

Excessive bouncing, a harsh or unsettled ride, reduced control over bumps, or fluid leaking from the shock body are common signs. Diagnose the cause before replacing.
