I recently purchased a ball joint for my automotive vehicle and my analysis of this product showed that it was a game changer. The Energy Suspension 9 13128R Ball Joint is a fantastic product for those looking for improved handling and a better ride experience .It was really easy to install and it made a noticeable difference in my vehicle's performance. The only con I have is that it is a bit pricey compared to other options in the market. Overall I'm happy with my purchase and I would definitely recommend it to those who are looking for improved handling and comfort..
