The fracturing dart may also comprise a second sealing assembly disposed proximate to the central shoulder section and configured to engage a seat formed in the internal bore. The fracturing dart may also comprise one or more shear pins that engage the upper cylindrical section of the body and are configured to shear upon the application of a predetermined force in a downhole direction within the wellbore.
