Replacement LCA or just bushings?

Has anyone used the full replacement LCA from RockAuto or similar?
My bushings have play and ball joints are oozing so it's about time to replace them.

It looks like ~$50 per side for get just the bushings and BJ.
Or, for ~$125 per side, they have LCA with BJ and bushings already assembled.

Seems cheap so just wondering who has tried these.

Are the OEM ones aluminum too? I wouldn't go with anything but OEM or a built one with a uniball if you were to replace it IMO.

 

I don't think they're aluminum. That's just the generic wording they use for all versions of the arms. They say it'll match whatever OEM is made of for each vehicle. The "(where specified)" statement.

so...
bump.

anyone tried them?
