Looked thru the forum for ideas, hit most of the suggestions already

I have a 2002 Durango with the tow package
NEW 5.9 engine,
tranny kit installed
rebuilt rear end with aftermarket cooler
10,000 load distribution hitch

Plenty of power, engine did not even grunt going up hills in Nevada pulling 6K 28 foot trailer

The problem is wind and sway from oncoming trucks
So my question is how to beef up the suspension

Firestone Load Leveler Air bags...or alternates?
Sway bars?
Air shocks?

Any other ideas?

Thanks in advance

 

Definitely one of the cheapest and most common mods, are the rear airbag suspension kits like I got. I'm not sure what brands/models to use though. Mine came on my truck when I got it a few weeks ago and I'm unsure what brand they are.
