Their first United States tour was in August 1988, when they opened for Larry Norman and played as his backup band. In fall of that year they toured for two months throughout Europe. together with Bloodgood and concluded the year playing the Ennepetal Christmas Rock Night festival in Germany for the second time. In 1989 they did touring again in Australia and completed two tours in the USSR. The same year they recorded Knights of Heaven in Los Angeles, produced by John Elefante. Before breaking up in the latter part on 1990 they again toured in the United States and Canada. The band did make an American appearance at the "Cornerstone" festival in Bushnell, Ill., the weekend of July 4, 1991. The band re-formed in March 2003 to play at the final Bobfest.

Side projects
Gomer and Haw joined with drummer Little George to form Jet Circus in 1988. Jet Circus's first album, Step On It, had a proto-rapcore sound. It was distributed in Europe by Pila Records, and introduced to the United States by Doug Van Pelt, Editor of HM Magazine. Despite quality issues due to its mastering Van Pelt dubbed it "the most creative release in Christian metal in 1990." After a long hiatus the band released No Mercy For The Living Dead in 2003. Ez also released a solo album – which became a Jet Circus album, when Terry left the band – entitled Look At Death Now in 2005. This album features artists including Mikkey Dee of Motörhead, Stefan Elmgren of HammerFall, and The Swedish Radio Symphony Orchestra. They have since released a remix album entitled Dance or Die. Following the end of Leviticus, Stigsson formed XT with Sonny Larson. XT released three albums. Stigsson also released a solo project in 1987 entitled Together With Friends.
