The shroud includes one or more positioning tabs configured to engage one or more corresponding alignment features of a mating component to radially position the shroud at the mating component, the one or more shroud positioning tabs position the outer shroud to define a radial tip clearance between an outer shroud and an adjacent rotor of the gas turbine engine. A gas turbine engine includes a stator and case assembly in fluid communication with a combustor. The stator and case assembly includes a stator located at a case. The stator has a plurality of stator vanes and a shroud including one or more positioning tabs configured to engage one or more corresponding case alignment features to radially position the shroud at the case.
