Ford HC3Z-99439A00-A & HC3Z-99439A00-B Genuine Tailgate Top Rubber Bumper Cushions — for 2017–2022 Super Duty

A squeaking, rattling, or grinding noise when closing the tailgate, or a tailgate that does not sit flush against the truck bed — these are common signs that your tailgate top rubber bumpers may need replacement. These rubber bumpers cushion the tailgate when it is closed, preventing metal‑to‑metal contact and ensuring proper alignment. A worn or damaged bumper can cause noise, misalignment, and potential damage to the tailgate or bed. Replacing them with this genuine Ford pair restores proper tailgate function and a smooth, quiet operation.

This is a factory‑original Ford tailgate top rubber bumper pair (OE part numbers HC3Z-99439A00-A for the left side and HC3Z-99439A00-B for the right side), specifically designed for the 2017–2022 Ford F-250, F-350, F-450 Super Duty. This pair includes both the left‑hand and right‑hand rubber bumpers, essential for proper tailgate alignment. The bumpers are made from durable rubber that withstands the forces of daily use and temperature changes. This is the same part sold at Ford dealerships.
