Firm up the ride and keep body motion under control with the KYB Gas-a-just Suspension Shock Absorber KG5538, a high-pressure monotube gas shock for cars and trucks. It installs in the rear position as a direct-fit replacement for the 1966-1974 FIAT 124, 1977-1981 Toyota Pickup, 1984-1989 Toyota Van, 1986-1988 Nissan Multi, 1986-1988 Nissan Stanza, 1988 Toyota Van Wagon, 1993-2002 Mercury Villager, 1993-2002 Nissan Quest, and 1995-2002 Toyota Tacoma — see the Buyer's Guide tab for engine-level detail.

  • High-pressure monotube design: separates the gas and oil for fade-free operation and instant response, unlike a traditional twin-tube shock that can aerate.
  • Two 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.
  • Triple chrome-plated piston rod: an ultra-smooth rod helps reduce seal wear, since fluid leaking can be a cause of shock failure.
  • Added damping: adds up to 25% more damping over original equipment, designed for vehicles that work, tow, and run larger, heavier tires and wheels.

The higher gas pressure is designed to improve steering response and helps keep electronic safety systems performing as the vehicle manufacturer intended.
