ResumoVe present self-dual spin-3 and 4 actions using relevant Dreibein fields. Since these actions start with a Chern-Simons like kinetic ter m (and therefore cannot be obtained through dimensional reduction) one might wonder whether they need the presence of auxiliary ghost-killing fields. It turns out that these actions must contain, even in this three dimensional case, auxiliary fields. Auxiliary scalars do not break self-duality since their free actions do not contain kinetic terms. RESUMEN. En este articulo presentamos acciones autoduales para campos de espin-3 y 4 usando la representacion triadica. Como estas acciones contienen como termino cinetico un termino generalizado de Chern-Simons, es natural preguntarse si, tambien en ese caso, se necesitan campos auxiliares para matar a los fantasmas. Resulta que estas acciones deben contener, aun en este caso tridimensional, campos auxiliares. Los escalares auxiliares no rompen la autodualidad de la accion complexiva puesto que sus acciones libres no contienen terminos cineticos.
