Dispelling the myth about slave cylinders
GM slave that came out of my car.
Autozone Slave
Now, I'm not saying the Autozone slave isn't a decent piece. I haven't used or even installed it yet. It is NOT however the same. The one that was in my car and has been used for god only knows how long looks like it was made MUCH better. The base of the AZ piece looks like they took a GM piece and made a sand cast to reproduce it, and the throw out bearing is completely different. The factory piece, as you can see in the first pic, has USA in the casting and the one from AZ is made in Ol Mexico.
I decided to still run the AZ slave b/c of the numerous members here that have said they've ran it and it worked fine, along with the fact that it was $70 out the door and has a lifetime warranty. If it gives me problems then I will just switch it out.
Thoughts?

There the same, GM used 2 different looking throw out bearings, the one like your on factory slave, and one like your AZ slave. I also picked up an AZ slave a few weeks ago, when i pulled my factory slave out it had the exact same throw out bearing as the AZ slave.
GM doesn't make slave cylinder's AP does. Not that it really matters, I don't see why everyone want's to argue about it. Just like you said the AZ slave comes with a lifetime warranty, does the "GM" slave? Hell no

The OEM is a quality piece -if you can pay the price. Just saying. Don't know how many times you want change it, no sweat off their ***** to give you another and shove it back up the vendor's ***. Not flaming you -I hope it really works out, let us know afterward. Good luck.

This has already been dispelled long ago. As already stated AP makes the slaves. So weather you buy a GM unit or a Autozone unit its the same part. There was changes to the slave though over the years. If your car is a 98-99 and even some 00's you could have the older version. Now when you go to the parts store to get a slave you get the updated version. You cannot buy a stock OEM version of a 98-00 slave, all hydrolics sold are the version that went into the 01-02 models. That goes for slave & master cylinder.
If I remember correctly a member on here removed his stock master & checked it side by side against the duralast master from Autozone & everything was the same on the master. The sticker, casting marks, everything. but it was only $65 with a lifetime warranty VS the GM unit for over $100 with only a 1yr warranty. The difference on that part was the one from the dealer comes with a new braided line & already bled, the Duralast version does not.

I've got 3 GM slaves on me now, 1 from 98, 2 performance GM ones and now a vette slave. I also had opportunity to compare to a buddies 2 vette slaves as well.
The autozone parts are not the same. Something about the metal seems off. Matches the casting marks, but reeks of knockoff copy from China.

There was an issue with the delphi replacements leaking despite looking near identical. Quality of the cast and material used to create can make a huge difference in the final product. It just feels wrong when you hold both pieces in your hands despite having the same everything. All the official GM ones felt well built, consistent for the ones I have on hand.

While I have replaced my slave with each clutch change, I have not had a single GM performance one fail on me. I'm now running a Corvette part piece, but aside from the connectors (which I switched over) and the throwout bearing, they are near identical.
The GM performance piece seems to be a good quality piece. It's $135 at summit.
