Firm up the front end and control every mile with the KYB Gas-a-just KYB shock absorber KG54309, a high-pressure monotube gas shock that mounts in the FRONT position. It installs as a direct-fit replacement for the 1995-2001 Ford Explorer, 2001-2003 Ford Explorer Sport, 2001-2005 Ford Explorer Sport Trac, 1998-2011 Ford Ranger, 1998-2007 Mazda B3000, 1998-2009 Mazda B4000, and 1997-2001 Mercury Mountaineer — see the Buyer's Guide tab for engine-level details.

  • Gas-a-just monotube design: two separate chambers — an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen gas area with a floating piston — so it doesn't fade from aeration.
  • High-pressure monotube: separates the gas and oil for fade-free operation and instant response, and the higher gas pressure helps improve steering response.
  • Triple chrome plated piston rod: since fluid leaking can be a cause of shock failure, the ultra-smooth rod is designed to reduce seal wear.
  • Extra damping: adds up to 25% more damping over original equipment shocks for vehicles that work, tow, and run larger, heavier tires and wheels; valving is designed specifically for Ford trucks.

It also helps keep Electronic Safety Systems performing as designed. Sold individually; order two to replace the front pair as a matched set.

Frequently Asked Questions

Is this a KYB gas shock absorber Excel G or a Gas-a-just?

This is the KYB Gas-a-just, a high-pressure monotube gas shock, not the Excel-G line. Its monotube design separates the gas and oil for fade-free operation and instant response.

What position does the KG54309 mount in?

It is cataloged as a FRONT shock absorber for the listed applications. Confirm fitment for your specific vehicle using the Buyer's Guide tab.

Does it fit my 1998-2011 Ford Ranger?

Yes. This shock is a direct-fit replacement for the 1998-2011 Ford Ranger, along with several Ford, Mazda, and Mercury applications listed in the Buyer's Guide tab.

How much damping does the Gas-a-just add?

KYB states it adds up to 25% more damping performance over original equipment shocks, with extra damping for vehicles that work, tow, and run larger, heavier tires and wheels.

Should I replace both front shocks at once?

This shock is sold individually. Replacing both front shocks as a matched pair is recommended for balanced, even ride control.
