LCA differences

What is the difference with the ACDelco Professional and ACDelco GM OEM lower control arms on Rock auto?
Which is better? Prices are only a buck or 2 different but what to get the better of the 2.
Thanks for any clarification on this.

I suspect that one is cast AL and one is welded stamped steel. All HHRs came from the factory with cast AL. Most Cobalts came with welded stamped steel.

They are both cast, the professional says fits Panel FE1 softride or LT FE3 Sport ride????
I just went with the GM OEM, couldnt find any differences in their listing and the prices were just a few bucks different. I also ordered new bolts. My drivers side is starting to shimmy more during braking so its time to fix it. Going to do both sides

Generally, ACDelco professional is lower quality.

I just drilled out the old ball joint rivets and bolted in new Moog ball joints and pressed in a new set of FE5 solid bushings, recycled the aluminum LCA’s


Old original hinge type FE3 bushings also same as FE1

New solid FE5 bushings

New Moog ball joints

Old dry loose original ball joint , 9 years and 130,000 miles

Yeah, I plan to rebuild the old ones with MOOG and keep for later if they ever need changed again.
