Default Stock 2.0 and 2.5 pistons and offset

Do stock 2.0 and 2.5 pistons come with offset pin.

If No could the use of forged pistons with offset in a 2.5 which has a less than ideal rod ratio allready result in increased bore/piston wear and could this increase in bore loading be the cause of may split bores and failures in the 2.5.??

They both do ,Not sure about that causing the splits in the bores though?
I would think w/ out the offset wrist pin some increase in sidewall loading but prolly not enough to split the cylinder , usually that's from having it bored & reducing the thickness of it IMO.
