KYB 554369 front shock absorber for the 2008-2019 Ford E-350 Super Duty and other vehicles damps spring and wheel movement with a high-pressure gas monotube design. This KYB shock absorber is a Gas-a-Just unit with up to 25% more damping performance over original equipment shocks, added for vehicles that work, tow and run larger, heavier tires and wheels.
- KYB Gas-a-Just high-pressure monotube design separates the gas and oil for fade-free operation
- Two working chambers: an air-free hydraulic piston and valve area, and a high-pressure nitrogen gas area with a floating piston
- Ultra-smooth triple chrome-plated piston rod to reduce seal wear
- Higher gas pressure responds quickly to improve steering response
- Instant, automatic adjustment to performance needs
Quick facts

Frequently Asked Questions
Is the KYB 554369 front shock absorber right for the 2008-2019 Ford E-350 Super Duty?
Yes. KYB 554369 is listed for the front of the 2008-2019 Ford E-350 Super Duty and for other Ford models. If your truck or van is a different one, check it in the "Vehicles it fits" section.
What sets this KYB Gas-a-Just shock absorber apart from a twin-tube design?
KYB 554369 is a monotube with two chambers: an air-free hydraulic piston and valve area, and a high-pressure nitrogen gas area with a floating piston. It does not fade from aeration.
Why does this KYB absorber have a triple chrome plated piston rod?
Fluid leaking can be a cause of shock failure, so the ultra-smooth triple chrome-plated piston rod on this front shock is there to reduce seal wear.
Does this front shock absorber help keep electronic safety systems performing as designed?
Yes. Electronic safety systems depend on the suspension, brakes and tires operating as the vehicle manufacturer intended, and this shock absorber helps keep them performing as designed.
How much more damping does this KYB gas shock absorber add?
Damping performance rises by up to 25% compared with original equipment shocks, and the extra damping is aimed at vehicles that work, tow or run larger, heavier tires and wheels.
