When you get them, if you have to install the bushings it should come with some grease for assembly. If it has zirk fittings on it, just use a good moly grease and grease them up when you install them. I usually regrease all my zirk fittings whenever I do an oil change.
I forgot...some aftermarket control arms come with with the bushings already installed and don't require greasing...I don't know the BBK ones that well so I'm not sure. If it has a zirk fitting then you can grease as required.
