I bought these for a 2007 Dodge Ram 1500 4x4 QC. (I bought both sides and my experience is the same with both) They are exactly the same in form and function as the original. I am totally impressed with them and they are almost identical to the original ones I took off my truck. They are even better than the original in my opinion because they have MOOG bushings and a greased ball joint. For the price, I don't think it's even worth replacing just the ball joint. If you push the old one out and the new one in, you can replace the entire part. I literally had every side replaced in less than 30 minutes using only hand tools including wheel removal. They are very nice things and I would buy them again at any time. After installation, the front part was leveled, there were no problems. The packaging also says MADE IN USA!
