KYB Suspension Shock Absorber P/N:KG5490

Firm up a bouncy rear end with the KYB shock absorber KG5490, a high-pressure monotube Gas-a-just gas shock cataloged for the rear position. It installs as a direct-fit replacement across the 1991-2001 Ford Explorer, 2001-2003 Ford Explorer Sport, 2001-2005 Ford Explorer Sport Trac, 1991-1994 Mazda Navajo, and 1997-2001 Mercury Mountaineer — see the Buyer's Guide tab for engine-level fitment.

The Gas-a-just 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. Because the gas and oil stay separated, it resists fade from aeration.

• Monotube gas design: high-pressure layout separates gas and oil for fade-free operation and instant response.
• Truck-specific valving: components and valving designed specifically for trucks, adding damping over OE design for vehicles that work, tow, and run larger, heavier tires and wheels.
• Triple chrome-plated piston rod: ultra-smooth rod reduces seal wear, since fluid leaking can be a cause of shock failure.
• Responsive damping: higher gas pressure adds up to 25% more damping over original equipment shocks and helps keep Electronic Safety Systems performing as designed.
