I'm interested in purchasing a 2/4.5 lowering kit for my 2007 Dodge ram quad cab 4X4. I was reading on some forum that the part number to fit it is 44015 or 44016. However when I look on mcgaughys website it does not show that they fit 4 x 4's . Do you know what kit will work? I really didn't want to spend the 1200 for the ground force
