In one aspect, a shank assembly for an agricultural implement may include a shank and a biasing element configured to exert a biasing force on the shank. The shank assembly may also include a reversible mounting plate defining a mounting aperture offset from a centerline of the reversible mounting plate such that a position of a second mounting location of the biasing element relative to a first mounting location of the biasing element differs depending on whether the reversible mounting plate is provided in a first orientation relative to the biasing element or a second orientation relative to the biasing element. The biasing element may exert a first biasing force on the shank when the reversible member is oriented in the first orientation and a second, different biasing force on the shank when the reversible member is oriented in the second orientation.
