The SM 5384 Starter Armature is a heavy-duty electrical component specifically engineered for the high-torque Delco-style (DEL. Type) starter motors used in Chevrolet’s premium diesel lineup. Featuring a precision-machined 12-teeth (12T) drive gear and high-density copper windings, this armature is built to provide the massive cranking power required for the 2.0L VCDi and common-rail diesel engines. The DEL-type configuration ensures a factory-standard fit, while the precision-balanced rotor and reinforced thermal insulation offer exceptional durability for the high-compression ignition cycles of luxury sedans and SUVs.
