A rod guide is provided for centering a sucker rod within a tubular string that powers a pump within a wellbore. The rod guide comprises a rotor secured to the sucker rod and having upper and lower stop surfaces thereon, and a sleeve formedfrom metal to substantially increase the life of the rod guide. The rod guide stator has an elongate slot extending along its axial length. The stop surfaces limit axial travel of the stator on the sucker rod, and the sleeve prevents the stator from engaging the sucker rod. The sleeve may be retained on the rod by a clip, and plastic end members then molded over the clip and the ends of the metal sleeve. The stopsurfaces may be formed by a ring member spaced axially between the upper and lower ends of the sleeve.
