Jeff Skinner scored twice, and Sebastian Aho and Teuvo Teravainen each had three points for Carolina, which completed an eight-game homestand 5-2-1. Cam Ward made 27 saves.
Anze Kopitar and Tyler Toffoli each had a goal and an assist for the Kings (30-21-5), who lost their second in a row. They are tied with the Anaheim Ducks, one point behind the Calgary Flames for third place in the Pacific Division.
"Totally disappointed," Kings coach John Stevens said. "Two teams fighting for a playoff spot, one team's in, one team's out. [Carolina] showed up to work and we didn't. It's pretty simple."
Jaccob Slavin gave the Hurricanes a 1-0 lead at 6:40 of the first period. He took a cross-ice pass from Jordan Staal, kicked the puck to his stick and lifted a backhand past Kings goalie Jonathan Quick.
Faulk made it 2-0 when he took a wrist shot from inside the blue line at 8:56 after taking a pass from Justin Williams.
Faulk's second goal, on the power play at 17:43, made it 3-0. He took advantage of Kopitar breaking his stick, and scored on a slap shot from above the face-off circles.
"I just saw something we could exploit a little bit on their penalty kill on that second one," Faulk said. "The puck was coming off the stick alright. I'm not going to turn down opportunities to shoot."
