Ring sets like this get matched to a specific bore diameter after a cylinder has been bored out to clean up wear or damage, and the +.060 designation tells you which oversize this set is meant for. Since we don't have more detail on this one beyond the basic listing, double check your actual bore measurement against this size before ordering.

Call the shop if you want us to confirm this is the right oversize for your rebore before it ships.
