Adrian Kempe and Arthur Kaliyev scored, and Cal Petersen made 21 saves for Los Angeles (5-5-1), which has won four straight.
"I think we'd all prefer the simpler win, where it's not in overtime or anything like that, but we don't always get what we want," Kings coach Todd McLellan said. "To deal with adversity has been a good thing for our team during the streak, finding ways to win. It would be easy to get down. We find ways to stick with it, so there's a lot of good things that are evolving. It's just a matter of sustaining them now."
Mackenzie Blackwood made 26 saves in his season debut after undergoing heel surgery in the offseason for New Jersey (4-3-2).
"We just got to find a way to give our goalies a little more run support because they've been so good for us," Devils defenseman Damon Severson said. "But overall, again, just the team effort tonight, you can't fault anything on that."
Kaliyev put the Kings back in front 2-1 at 16:20 of the third period with a power-play goal on a wrist shot from the left point. It was his third goal in the past four games.
"I told Arthur on the bench after the first power play, 'That's what you're here for. No one's going to ever get mad at you for shooting the puck the way you shoot it.' And he did. Good for him," McLellan said.
