i have the overload springs on mine and was looking this weekend at puting in air lift air bags. When i really got to looking at it the over loads have about a 3/4inch spacer and then the two leafs are about 1 and 1/2 inches. so that adds a little more than 2 inches. so will your airbag setup still work after you add the extra leafs in there? i'm not sure, just bringing up the point. Hopefully someone can answer my own question about if i can even put the airbags on my truck.
