    Just bought an 04 comp G and the LCAs are terrible, super bad. Rockauto has Moog LCAs for "R-Series", part numbers RK620675 and RK620676. Are these the correct LCAs for this car? Thanks for the help.

    Yep.

    I have the CK620675 and CK620675.
    Tighten them tight when you do them, crank the piss out of them, use a cheater bar and a 21mm long box wrench to squeeze em tight.

    R series are their budget R(icer) series. I've gone with cheap control arms before and they went bad after one year. Unless you like doing the same work twice go for a quality model and avoid the cheap crap. You get what you pay for.

    Can you substantiate your suggestion with brand/part number?

    04-05 (and some early 06's) have a different LCA than 97-03 and later 06-08's. You could still technically put the other LCA's on your car, you will just have an extra tab for a sway bar mount.

    Most people around here run Dorman LCA's. You can get them for around $50 a piece on Rock Auto.

    If you can get the dorman LCA police/Taxi for the 04 Chevy Impala, I would get them, if they will fit. I use the 01 Chevy Impala Police/Taxi LCA on my 01 GP. I also use the 01 Impala Police/Taxi Struts at all 4 wheels which are superior to the OEM Delco struts and the KYB's which are junk....

    Not ideal, but i ordered the base Moog LCAs and also those Moog ball joint style front bushings, and the Moog hard rubber (blue) rear bushings. Hope this will all go together and work.

    Has anyone used LCA part numbers 22947665 / 22947666 on a 97 - 03 Grand Prix, do they fit and is there a noticeable difference?
