Yes sorry, I was looking at the pic which is 1 piece, the description says 2 piece. They do come with a "balance" from the factory, but from what I hear they are not a good/accurate balance. More than likely they have a target weight/balance for each part and if they fall into a certain tolerance it is good to go, meaning the entire assembly/collection of parts you get is not holistically balanced. You can chose to trust the Chinese balance, but it is not suggested for any performance or RPM use. Low RPM grocery getter you are OK.
