Prevent tailgate slam and improve safety with this OEM Rear Non-Powered Tailgate Slam Prevention Damper Kit for the 2021–2026 Ford F-150, part number ML3Z-5D008-C. This genuine Ford “tailgate assist” system uses a viscous dampening cartridge to control the rate of descent when opening the tailgate, allowing it to lower smoothly instead of dropping suddenly. Engineered to Ford factory specifications, it is a direct replacement for the original damper kit and installs using factory mounting points and included hardware. Designed for trucks without a factory power tailgate system, it improves convenience, safety, and durability during daily use.
