KYB Suspension Shock Absorber P/N:KG54333

Firm up a working truck's ride with the KYB Gas-a-just Suspension Shock Absorber KG54333, a high-pressure monotube gas shock that installs as a direct-fit replacement in the REAR position on the 1999-2004 Ford F-250 Super Duty and 1999-2016 Ford F-350 Super Duty (see the Buyer's Guide tab for engine-level fitment). Its components and valving are designed specifically for Ford trucks, adding damping over the OE design for vehicles that work, tow, and run larger, heavier tires and wheels.

• Monotube design: Separates the high-pressure nitrogen gas from the oil for fade-free operation and instant response, avoiding the aeration that affects traditional twin-tube shocks.
• Two working chambers: An air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen area with a floating piston for a comfortable ride during normal driving.
• Up to 25% more damping than original-equipment shocks, and the higher gas pressure responds quickly to help improve steering response.
• Triple-chrome-plated piston rod: An ultra-smooth rod reduces seal wear, since fluid leaking can be a cause of shock failure.

KYB reports the Gas-a-just also helps keep Electronic Safety Systems performing as designed, since those systems depend on the suspension, brakes, and tires working as the vehicle manufacturer intended.
