Quad shocks (if not blown) will dampen wheel hop in the rear end. But it's not 100% proof, especially if the driver goes into WOT heavily. They can sometimes rub on the tires, so flipping them 180° may do the trick if you want to install 10" or 10.5" wheels and wider tires.
Now Ford's 4-link suspension is not the greatest, it will bind up. So you can help your rear suspension setup by completely removing the quad shocks. It's best to install a set of quality aftermarket lower control arms that will not have the flexabilty found in your stock or cheaper ones, and this will make the quads shocks an un-necessary suspension component on your car.
Now the hard part, quality matters. I would only select a lower control arm from a reputable suspension company like Maximum Motorsport, Griggs Racing, Racecraft, Cortex Racing or Steeda. And do your best to stick with one company when it comes to your suspension needs. Mixing components from different vendors sometimes comes with sub-par results.
Good luck
