Keep your Toyota truck planted through work, towing, and rough roads with the KYB Gas-a-just Suspension Shock Absorber (KG5437), a high-pressure monotube gas shock that installs as a direct-fit front replacement for the 1984-1985 Toyota 4Runner and 1979-1985 Toyota Pickup. See the Buyer's Guide tab for engine-level fitment.

Unlike a traditional twin-tube shock, the Gas-a-just monotube uses two separate 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 that supports a comfortable ride and adds damping on demand.

  • High-pressure monotube design: separates the gas and oil for fade-free operation and instant response.
  • Triple chrome-plated piston rod: ultra-smooth rod helps reduce seal wear, since fluid leaking can be a cause of shock failure.
  • Extra damping: adds up to 25% more damping performance over original-equipment shocks, with components and valving designed specifically for Toyota trucks.
  • Higher gas pressure: designed to respond quickly to help improve steering response and helps keep Electronic Safety Systems performing as designed.

Sold individually; replace both front shocks together as a matched pair for balanced damping.

Frequently Asked Questions

What vehicles does the KYB KG5437 shock fit?

It is a direct-fit front shock for the 1984-1985 Toyota 4Runner and the 1979-1985 Toyota Pickup. Check the Buyer's Guide tab to confirm the fit for your vehicle.

Is this a front or rear shock?

The KG5437 is cataloged as a front-position suspension shock absorber for the listed Toyota applications.

How is the Gas-a-just monotube different from a twin-tube shock?

It uses two separate chambers—an air-free hydraulic piston/valve area and a high-pressure nitrogen gas area with a floating piston—so the gas and oil stay separated for fade-free operation and instant response.

Do I need to replace both shocks at once?

Each shock is sold individually. Replacing both front shocks together as a matched pair is recommended for balanced, even damping.

What interchange numbers does the KG5437 replace?

It cross-references G63404 and 37031. Match your original part number and confirm the application before ordering.
