A vehicle tailgate movement assist mechanism including a tailgate configured to rotate between opened and closed positions and a tailgate lever arm fixedly connected to a bottom area of the tailgate. A drive lever may be pivotally connected at one end thereof to the tailgate lever arm and pivotally connected at an opposite end thereof to a bell crank. The bell crank may be pivotally anchored at one end thereof to a vehicle body, and a plunger damper may be anchored to the vehicle body adjacent the bell crank. With the mechanism configured as discussed above, rotation of the tailgate from a closed to an opened position simultaneously rotates the tailgate lever arm to impart movement to the drive lever and the bell crank to thereby contact and actuate a plunger of the plunger damper to reduce an opening speed of the tailgate.
