OK. Today I bought and hauled 500 lbs. of rock for a very small landscaping project. You would have thought I loaded it to the top of the bed rails, (not even close!) and my 1500 was squatting something silly. So, I have decided to give the, "Air Lift 1000" airbag a go. According to what I could find the part # I need for my 2010 4WD 1500 is, 60808. Does any member know if that is the correct part #??. Also, is it necessary to buy the, inflation kit or does each bag have an air line coming out of it for inflation/deflation?? Also, where is a good place to purchase? Thanks.
