Rear suspension raising

Why do you want to raise it? To carry a heavy load or to put 24" wheels on it?

I carry about 300 pounds in my trunk of equipment they hit pounds but the car was low already to begin with two and three quarters inches short driveway so I need to raise the body at least 2 inches if possible I put on the hitch only to put a storage carry on the back

I think you may have a hard time finding heavy duty springs for your car as everything available is for lowering. I would go to shop that does alignments and suspension work and see what they can do. Maybe some custom made heavy duty springs would help you.

Not a company car. Sorry if not clear, (using smartphone before) My 2014 Fusion just sits far too low even before putting on my Curtis Hitch. My 2.5 liter can tow up to 1000 lbs (2,000 if it were a 2.0 turbo). Want to increase height, there is no factory or aftermarket options. I'm left with https://www.pepboys.com/product/details/951906/00786/ or smaller ones: https://www.pepboys.com/product/details/271374/00786 I was told two different things by two shops put in the spring or put on the base or top? Not sure which is better the big one is really big but might give me the 2 plus " I would like. Air shock (mick more expensive and no real application available

You should have bought a SUV

I got taller and wider tires on the rear of my Ford fusion but the rear tires are rubbing when I make a turn I want to get either AIR SHOCKS OR GAS SHOCKS TO lift my tires so they don't rub
