1984 and 1985 were the best seasons of Curicó Unido history, disputing the promotion until the last week, but with bad luck at the final matches.
The next campaigns were average, with the exception of the season 1990, when they lose the category after the final match with Deportes Valdivia, when they won 4–1, two goals short what they needed to stay at Primera B.
Curicó Unido's official kit is a white shirt with a diagonal red stripe that crosses the chest from the right shoulder to the left side of the hip.
They also played their Tercera Division league home games of the season 1992, at the Estadio ANFA Luis H. Alvarez.
Curicó Unido supporters' current main rivals are Rangers de Talca, and Ñublense.
