A vehicle tailgate lift system comprises an energy storage device located within a vehicle body and adapted to be pivotally anchored to the vehicle bo dy at one end, a bellcrank arm that is pivotally attached to the energy storage device and rigidly attached to an actuation shaft that is coaxially aligned with a tailgate pivot axis, a pivot bracket assembly that incorporates a piv ot bearing arrangement to facilitate a robust rotary joint about the tailgate pivot axis, and comprising a coupling means between the tailgate and the actuation shaft, such that relative rotary motion of the tailgate and vehicl e body results in linear movement of the energy storage device and maximum energy storage at the tailgate fully open position.
