KYB Suspension Shock Absorber P/N:3440013
Bring firm, fade-free control back to your work truck with the KYB Gas-a-just Shock Absorber 554347, a high-pressure monotube gas shock that installs as a direct-fit front replacement for the 2005-2024 Ford F-250 Super Duty, 2005-2025 Ford F-350 Super Duty, 2005-2016 Ford F-450 Super Duty and 2005-2022 Ford F-550 Super Duty. This KYB shock absorber uses a monotube design that separates the gas and oil into two working chambers, so it resists the aeration-related fade of a traditional twin-tube unit.
Sold individually; order two for a complete front-axle set. See the Buyer's Guide tab for the full engine-level fitment.
Will the KYB gas shock absorber fit my Ford Super Duty?
It is a direct-fit front replacement for the 2005-2024 F-250, 2005-2025 F-350, 2005-2016 F-450 and 2005-2022 F-550 Super Duty. Check the Buyer's Guide tab to confirm your exact vehicle and engine.
What makes this a monotube gas shock instead of a twin-tube?
The monotube design keeps the gas and oil in two separate chambers, which helps it resist the aeration-related fade a traditional twin-tube shock can experience.
Does one listing cover both front shocks?
No. This KYB shock absorber is sold individually, so order two to replace the full front axle for even, balanced ride control.
How much more damping does the Gas-a-just add?
Per KYB, the Gas-a-just adds up to 25% more damping over original-equipment shocks, with components and valving designed specifically for Super Duty Ford trucks.
What are common signs my front shocks may need replacing?
Signs can include excessive bouncing, nose-dive under braking, poor ride control, or fluid leaking from the shock body. Have the suspension inspected to confirm the cause.
