KYB Suspension Shock Absorber P/N:3440022
Steady the ride and help restore factory control on your Super Duty with the KYB Excel-G Rear Shock Absorber 344382. It's a direct-fit rear replacement for the 1999-2004 Ford F-250 Super Duty and 1999-2004 Ford F-350 Super Duty (see the Buyer's Guide tab for engine-level fitment). KYB is a world-leading supplier of shocks and struts to new-vehicle manufacturers, and the Excel-G is built on the same KYB OE assembly lines with OE-quality components — calibrated to restore the vehicle's original designed performance, not change it, which earns it the OEA (Original Equipment for the Aftermarket) classification.
Shocks wear as a set — replacing both sides on the axle together is best practice for balanced, even ride control.

Is this a front or rear shock?
This is a rear-position shock absorber. It installs at the rear of the listed Super Duty applications.
What type of shock is the KYB Excel-G?
It's a nitrogen gas-charged, twin-tube gas shock that includes the same quality components found in KYB's global OEM products, earning it the OEA (Original Equipment for the Aftermarket) classification.
Should I replace both rear shocks at the same time?
Shocks wear together, so replacing both sides on the axle as a matched set is best practice for balanced, even ride control. This listing is for one shock.
What does the triple lip fluid seal do?
The triple lip fluid seal is designed to reduce the chance of oil and gas leaking out of the shock, helping it maintain consistent damping.
