In 1982, guitarist Ronnie "10/10" Younkins was fired and replaced by Brad Divens (Souls at Zero/Wrathchild America/Wrathchild),Their 1983 followup, Cool Kids, showcased a markedly more commercial side of the band, featuring the title song, and the single "Body Talk".
In 1983, having been gone for slightly less than a year, Ronnie "10/10" Younkins returned to Kix, reuniting the "classic" lineup.
Kix then partnered up with RATT, Warrant and Winger producer, Beau Hill, and in 1985, released the album Midnite Dynamite, featuring a hard rock single by the same name and funk rock songs "Cold Shower" and "Sex". The album also included the song "Bang Bang (Balls of Fire)", which was co-written by Purnell and Kip Winger. Outside players such as session drummer Anton Fig who played on two tracks,as well as Mike Slamer (Streets/City Boy/Warrant)who receives credit for additional guitars helped redefine the band's sound. With this new sound Kix would now be at the forefront of the Hair Metal genre alongside contemporaries Warrant,Poison and Winger. Kix went back into the studio to record more of Donny Purnell's songs. In 1988, they released Blow My Fuse, and finally achieved fame as it went platinum. The slow ballad "Don't Close Your Eyes"—containing anti-suicide lyrics—led the way (peaking at #11 on the Billboard Hot 100) and other popular cuts followed. The album featured the popular singles "Cold Blood" and "Blow My Fuse", along with popular videos showing the band in concert at Hammerjack's. In 1989, the band released Blow My Fuse: The Videos, with their now-popular videos and behind-the-scenes footage. As Kix finally graduated to arenas, they opened for such popular artists as RATT.
The album Hot Wire arrived in 1991, with the single "Girl Money". In 1992, guitarist Jimi K. Bones replaced Brian "Damage" Forsythe. While on tour in 1992, they made a live album, titled Live at the University of Maryland, College Park. This album, internally referred to as Contractual Obligation Live, was released in 1993. In 1994 Atlantic dropped the band from that label. In 1995, the band released their final album, Show Business, on CMC International.
