A surgical reload includes a proximal body portion defining a first longitudinal axis, a tool assembly defining a second longitudinal axis, and an articulation stabilization system. The tool assembly is pivotably supported on a distal end of the proximal body portion between a non-articulated position in which the first and second longitudinal axes are coaxial and articulated positions in which the first and second axes define an acute angle. The articulation stabilization system is configured to urge the tool assembly in relation to the proximal body portion to the non-articulated position.
