Hey guys I bought these pistons a couple weeks ago and was told they were Mahle pistons. I talked to technical support this morning cause I couldnt find a part number that matched on their catalog and they said its not theirs?! Can anyone tell me whos pistons these are? The only thing stamped on them is GA-.50/S. Here is a pic of them and you can see whats stamped on them. Any help would be greatly appreciated. Thanks.

Tony.

Can you post a side view? And also up inside the piston from the bottom. Just one piston, so that small details are maximized.

At first glance they look like OE Terminator pistons. I have a few at the house I can look at, but none with me right now.

If you can check against what you have that would be awsome. I would really like to know what pistons these are. Anyone else?

Just took my Aluminator apart and they have Mahle pistons. Don't know if this will help but here are a couple pics.

Just looked at mine, and those are 100% OE 03/04 terminator pistons manufactured by Zolner. The Aluminator pistons are Mahle. Zolner is no longer around.

Thanks for posting piston pics. What part number is that on the piston head(can't read it too well)?

You haven't by chance mic'd the bore and the piston at it's largest ellipse??

Thanks

No I did not. I have already shipped the pistons to lOOKnGO maybe if you pm'd him he could give you the numbers off of the pistons. I had it written down but can't seem to locate the paper I wrote it on.
