KYB Suspension Shock Absorber P/N:KG5439

Smooth out the ride and restore firm damping control with the KYB Gas-a-just Shock Absorber KG5439, a high-pressure monotube gas shock built as a direct-fit replacement for 1980-1996 Ford Bronco, 1980-1996 Ford F-150, and 1975-1976 Ford P-400 (see the Buyer's Guide tab for engine-level fitment). This KYB shock absorber uses a monotube design with components and valving developed specifically for Ford trucks.

• Two working chambers: An air-free hydraulic piston and valve area for responsiveness and control, plus a separate high-pressure nitrogen gas area with a floating piston for a comfortable ride during normal driving.
• Fade-free operation: The high-pressure monotube separates the gas and oil, so it does not experience fade due to aeration and responds instantly on demand.
• Extra damping: Adds up to 25% more damping performance over original equipment shocks — designed for vehicles that work, tow, and run larger, heavier tires and wheels.
• Durable piston rod: An ultra-smooth triple-chrome-plated piston rod helps reduce seal wear, since fluid leaking can be a cause of shock failure.

Its higher gas pressure responds quickly to help improve steering response, and KYB notes it helps keep electronic safety systems performing as designed. Where your application uses this part at the front or rear position, it installs as a direct-fit replacement. Sold individually; replace shocks in axle pairs for balanced control.
