KYB Suspension Shock Absorber P/N:553385

Fluid leaking from the body, a bouncy ride or rear-end sway can mean this shock absorber is worn. Worn tires or tired rear springs can produce that bounce too, so find the cause before you replace it.
These are shock absorbers for the 2009-2025 Ford F-150, which takes two at the rear. This listing is one shock absorber; the other side of the rear axle is normally done at the same time.

This part cross-references / interchanges with the following part numbers:
Is the KYB 554373 shock absorber the right one for the 2009-2025 Ford F-150?
Yes. KYB 554373 is a rear shock absorber for the 2009-2025 Ford F-150, and that truck takes two.
Is this KYB gas shock absorber a monotube or a twin-tube design?
It is a high-pressure monotube. Gas and oil are kept apart, with the nitrogen gas area and floating piston separate from the air-free hydraulic section.
Does the KYB rear shock absorber have a chrome piston rod?
Yes. The KYB 554373 piston rod is triple chrome plated and ultra-smooth to reduce seal wear.
How can I tell if a rear shock is leaking?
Oil wetting the shock body or rod, visible from beside the vehicle with the engine off, can mean the shock is leaking. Fluid leaking can be a cause of shock failure, and a shop can inspect it further.
Does this shock absorber help electronic safety systems?
Yes. This shock absorber helps keep electronic safety systems performing as designed, since they depend on the suspension, brakes and tires working as the vehicle maker intended.
