The Kings (40-27-10) are three points ahead of the Vegas Golden Knights, who have a game in hand.
Phillip Danault scored for the third straight game, Jonathan Quick made 21 saves, and Los Angeles ended a three-game home losing streak.
"Obviously, the last game, we were not satisfied, not happy, so we had to bounce back, which we did right away in the game," Danault said, referring to a 9-3 loss at the Colorado Avalanche on Wednesday. "Big two points, and every single game is going to be big until the end, so it's a do or die."
