What brand are these LM pistons?
I have a box of these with rings that look barely used. Wondering why someone took them out...

That is a GN piston. The same thing as what Clark's sells.

Because in high performance use, they crack at the end of the oil ring groove.
And these type also more easily crack because they are cast and brittle.
Detonation is not friendly to to them either.
Find for low HP street use and " Trailer Queens "

Are they better than stock pistons?
