They are 4x4 items as the 2wd ones have a flat 2 pence diameter in the center

I have recipts that came with the car for brand new mahles being machined to 7.2:1, but you can't always trust recipts lol

Also none of us know what machined pistons look like, so thought it best to ask

Paul if there are no markings on the piston then they have been modded but as for comp ratio you will have to measure to be sure
