On July 2, 2007, Preissing signed a four-year, $11 million contract as an unrestricted free agent with the Los Angeles Kings. In the 2007–08 season, his first with the Kings, Preissing suffered in production, scoring only 24 points in 77 games, and his plus-minus slipped to –6. Preissing was benched for four games into the early stages of the 2008–09 season. After stepping up his play Preissing was then hampered by illness and upon recovery was assigned to the Kings affiliate, the Manchester Monarchs of the AHL on March 4, 2009, for the rest of the season.
