A ring set like this goes in when a cylinder has been bored out from standard, so the rings are sized to match that oversize bore rather than the factory dimension. If your barrels have already been bored .040 over, or you're having that work done now, this is the set that corresponds to that spec.
We don't have more detail on this one beyond what's in the listing, so give us a call if you want to confirm exactly what's included in the set before you order.
