Drivetrain Wheel Hop On Take Off

On my 90' GT when I take off, it feels like it is almost wheel hopping and I can feel a lurch or jumping from the rear end. I just swapped gears over the winter, got new maximum motorsports upper and lower control arms, new quad shocks and axle bushings. Any idea what could cause this? I am out of ideas since I replaced everything I thought could cause it and I'm not driving aggressively when it happens.
