A downhole drilling motor comprises a housing including an integral stabilizing configuration. The stabilizing configuration may include a number of ribs which project from the surface of the housing and run longitudinally or helically along the housing. The stabilizing configuration may be a result of the cross-sectional shape of the housing which may be substantially triangular or square such that the diameter of a circle which circumscribes the cross section of the housing is substantially the same as the diameter of the borehole within which the motor may be used.
