I have seen those thicker pistons also & it seems to me it would be defeating the purpose. These re builders put them in thinking it is more durable. If you notice every one like that has some kind of rebuild sticker or stamping, & the metal tag is gone. The tiny rod goes in & knocks the ball off the seat letting more gas go through. A thicker rod or one that blocks the hole is not right. I would use the original thin one.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
