Excelente calidad en materiales, resistencia y practicidad
Excelente producto, de muy buena calidad y a un precio accesible, funciona de manera excelente, se la instalé a mi Jeep Cherokee y ahora tiene más fuerza, agarre y fricción en su trabajo de eje traseroz ahora puedo ir a lugares donde antes no me era posible acceder cuando los ejes no eran positivos, 100% recomendado
