A seal assembly includes at least one blade outer air seal (BOAS) including a base portion that extends between a leading edge and a trailing edge. A forward wall and an aft wall extend radially outward from the base portion to a radially outer portion. The radially outer portion is spaced from the base portion and at least partially defines a passage with the forward wall, aft wall, and base portion. At least one attachment body is located at least partially within the passage. The at least one attachment body includes a leading edge connected to a trialing edge by a radially inner surface and a radially outer surface. The radially outer surface includes at least one blade outer air seal attachment surface for engaging the at least one BOAS. At least one post extends from the radially outer surface and has a blade outer air seal guide surface.
