2004 towing upgrade

[SBodoh]

I have a 2004 Expedition Eddie Bauer with the factory tow package. I don't have the HD. I want to be able to haul a larger trailer.

What should I upgrade to get closer to the HD weight limit? I already have a WD hitchx 7-way plug and brake controller. I also want to find something to help level the rear end when I tow. I installed new loaded struts and it helped but not for heavier loads. Is there some type of aftermarket upgrade out there?

Thanks.

Do you have Equalizer bars on the hitch If so are the properly rated for the tongue weight and load.

What is the gross weight of the trailer you are planning to tow.
