my trucks run good with the stock suspension,the 06 lbz 2500HD crew,shortbed i pulled 10k with it,all i can say it pulled it with ease,it wouldn't hurt to have the sway bars.on the dually it came out off kentucky with a load of logs hit the scales at 41k,after that i did consider airbags but i don't plan on hauling like that again.hope this helps.ps drive carefull with any load
