Are these pistons ready to install right out of the box?

Yes, these Mahle OE pistons come with the piston rings already mounted. The set also includes the necessary pins and clips, making them ready for installation into your engine.

What does the '.010' in the part description mean?

The '.010' indicates that these pistons are 0.010 inch undersize. This is a common size for engine rebuilding when cylinders may have been honed or bored slightly.
