    Hey guys I ordered 2 Moog lower control arms from Amazon the other day and they came in today. They are supposed to be Moog RK620676 and RK620675. They sent the exact same part both times even though the box has the correct model number on them. I believe it's the right side one both times. I plan on returning it to get the right part but I had a question first. For anyone that has these already, is this what they are supposed to look like? I'm just curious because it doesn't say Moog on them at all or have any kind of model number either. Perhaps that's the way it really is, but I just find that a little odd. I've attached a picture of the two parts so you guys can see. Thanks for the help.

    They do look like the dorman one I got today but the castle nut on the dorman is grey on mine, that one is silver. There will only be small differences I'm sure, mine has some paint marks on it and the dorman logo. Funny you got problems with your LCA purchase, as did I. They were supposed to put both sides in the same box and they'll both have the same tracking number. Well they did have the same tracking number but only put one in the box...

    That's right ^ Good way to distinguish them. So you need to contact them telling they sent you two right arms, and that you need one replaced with a left, RK80539. Amazon is good with returns, I ordered from ebay and they're very good with making sure you get what you ordered too.

    But seriously? What is it with people? You order two very similar products and their brain can't handle it or something.

    Not neccessarily true. The RK series are the low end model that does not have grease fittings. The CK series are the one's with the grease fittings.

    Did you mean RK80539? I'm pretty sure that is the left side LCA that I need, but if I'm wrong please correct me.

    I just installed MOOG LCA part numbers RK80538 and RK80539 I bought from rock auto. Unfortunately I didn't take any pics of them before, but they both have grease fittings.

    I actually meant RK620676. I ordered the RK620675 so I'd like it to match. Plus Amazon says the RK80539 doesn't fit my car.

    How much better is the CK series than the RK? I can get it for about $30 more so is it worth it?

    Ok that's where the mismatched numbers came from. The RK is apparently not actually made by moog, just a re-labeled cheaper version so moog can still sell a lower priced item, I'd take the dorman over the rk version(if dorman even makes one for your year). CK is good moog quality though.
