Why?

Better off getting a block with forged pistons in it. The RA pistons aren't any better. Still the same cast crap.

From what I saw in the photos posted here is that the pin boss area was beefed up. The ringland thickness was the same though. Factory pistons weren't cracking at the pin bosses were they? Typically the piston would have a ringland failure before the power levels and rpm wiped the motor. Also the area where the most material was added would more benefit increased rpm.

I never said they were going to be any stronger. I am curious if they had a material change, but even with that, it'll have minimal gain over the old pistons.

I was simply stating that the pistons aren't the same, but they are still cast.
