There is a thrust side, it's offset, it happens to keep the small end of the rod near center of pin boss.
You don't really want your rods rubbing/ bouncing off the pistons pin boss, you want less friction...not more.
There's pin offset, which is the piston (some pistons...) and there's beam offset which is what YR and I were talking about. If you're talking offset in any rod, you're not talking about the pin end...
