For an NA mild rebuild they will do great. You can also get them for a stock rod if you want to try and save a few bucks.

i've seen mahle stamp on what was supposed to be "stock" ls6 shortblock. But they are cast and not performance "forged" pistons. Just from what i've read

I believe Mahle is a big OEM supplier.

Mahle builds pistons for LOTS of manufacturers. And yes, they are the O.E. piston in most of the LS motors.

Their Mahle Motorsports division is the "aftermarket" that you want to get. These would be forged racing pistons. They are a great piston, but Ive found that some of the alloys dont support big HP (800+).

I believe they will be some of the longest lasting, and quietest pistons you could get for a mild build.
