Abstract
A tailgate dampening system for a vehicle including a tailgate lift assist system including a torque rod rotationally grounded between the tailgate at a first end and a first side of the vehicle's frame at a second end is disclosed. The dampening system includes a coupling shaft attached to one end of the torque rod, a bell crank arm attached to the coupling shaft, and a dampening strut attached between the vehicle's frame and the bell crank arm. The crank arm compresses the dampening strut as the crank arm is rotated by the torque rod through the coupling shaft as the torque rod is twisted in response to the tailgate being opened, so as to reduce the rate at which the tailgate falls.
