KYB Suspension Shock Absorber P/N:344366
Firm up a working Ford truck or van with the KYB shock absorber (Gas-a-just, MPN 554369) — a high-pressure monotube gas front shock built for the 2008-2014 Ford E-150 and E-250, the 2008-2019 and 2021-2025 Ford E-350 Super Duty and E-450 Super Duty, and the 2008-2024 Ford F-250 Super Duty and F-350 Super Duty. See the Buyer's Guide tab for the full application and engine details.
This KYB gas shock absorber uses a monotube design that separates the high-pressure nitrogen gas from the oil, so it resists fade from aeration and responds instantly. An air-free hydraulic piston and valve area handles control while a floating piston in the gas chamber adds damping on demand.
