Can someone explain why they are forged and not just made out of solid at such a small quantity ? Is there a benefit to using the forging?

Stronger piston. Ring lands don't last as long due to being aluminum unlike our stock ones that have a steel ring land cast into them. You can coat the pistons and hard anodize them to help reduce wear. Some say it works and some say it doesn't.

Much much stronger.

That doesn't make sense if the same material is being used...Now if the place doing the forging of the pistons uses a custom material blend than that makes sense...Forgings have flaws in the inside of the material due to the process involved in forging.

The International pistons seem to be holding up just fine, for the price difference I'd go with them. Mainly for competition.

Race engine option. You could put them in but I was warned the ring lands sometimes only last 20,000 miles then you need to tear down. Some ppl get 80,000 miles out of them. There race parts.

Sorry Dennis but you don't seem to know much about high hp motors. The forging process vs the casting process is night and day. Hence the reason high hp motors use forged if they are available.

True, a forged part is always stronger. Some basic examples, forged cranks vs cast, forged wheels vs cast. The forged cranks have higher rpm and hp ratings, forged wheels like the factory alcoas are forged, like the semi wheels are forged thus offering a higher load capacity.

Stamped or cast parts do not have the material density that a forged part does.

True I don't know anything about high HP motors...I'm just a dumb kid machinist.
I didn't say compare forged vs cast... I said compare Forge vs machined out of solid...Forging is a volume process. I just wanted to know what the advantage was over turning these out of "billet" (hate this word as it is bull****).
