It's there ICON brand.
It's a forged piston not that other crap with the KB name.
I have used this brand a few times they seem fine. I will put then at the same level as like probe. But for a shelf piston and for no more than what I need them for there more then nice enough.
I'm work out doing another that looks like I'm going to offset grind the crank .090 and use a 2in small G Chevy rod at 6in long and bore it 4in.
The only thing is, looks like im going to have to put 6 flange sleeves in it.
