Abstract

A ball striking device has a head with a body member having a face having a striking surface configured for striking a ball, a crown portion and a sole portion connected to the face and extending rearward from the face, where the body member has a void extending inwardly from a rear periphery of the body member, and a rear member connected to the body member and received within the void, such that the rear member forms portions of a crown and a sole of the head. A connection member connects the rear member to the body member to form a joint between the rear member and the body member. A resilient member separates the rear member from the body member, and the resilient member engages the rear member and the body member within the void and is configured to transfer momentum between the rear member and the body member.
