You can specify a fixed-width fontfamily if that helps:

levelplot(matrix(seq(4,120,l=9),3,3),
          colorkey = list(at = seq(0, 120, 20),
                          labels = list(labels = c('  0',' 20',' 40','
60',' 80','100','120'),
                                        fontfamily = "courier",
                                        font = 1)))
