Think twice before buying a Moog part with the "RK” prefix. They are not made by Moog and do not meet the same standards. The ball joint pins on the control arm were upside down and damaged my car. Revane referred me to Moog, Moog referred me to Revane. If you are okay with poor quality haphazardly assembled parts, don't buy them. You can get this quality (or lack thereof) for a lot less elsewhere. It used to be that you pay a little more for a well-known brand to get the best. Suppliers and manufacturers also used to stand behind the parts they sold and produced. I have found that this is not the case with this transaction. Edit: After much negotiation, Revane came over and took care of my issue. Federal-Mogul didn't give me the time of day - told me I was alone because I bought them from an online store, "they buy from everyone". I still don't recommend these parts - buy something else.
