Two strong lensing systems, characterized by rich clusters with prominent blue arcs, were found in the Sloan Digital Sky Survey (SDSS). These systems, known as SDSS J1439+32 and SDSS J1343+41, had follow-up spectroscopic observations with the Mayall 4m telescope at Kitt Peak National Observatory. Using multi-slit spectroscopy, we measured the redshifts of the cluster member galaxies. Based on these redshifts, we will present the velocity dispersions of the clusters as well as estimates of the dynamical masses of the clusters.
