Aberg scored 45 seconds into the first period to give Edmonton a 1-0 lead. He collected a loose puck behind the net and tucked it in.
McDavid scored at 15:32 for a 2-0 lead, knocking in a second attempt after hitting the side of the net with his original tip off a pass from defenseman Adam Larsson.
"It's important to come down the stretch solid as a team," McDavid said. "And individually, guys want to feel good about themselves heading into the summer and build some steam heading into next year."
Muzzin made it 2-1 at 16:00. He took a pass from Tanner Pearson in the slot and picked the bottom corner on Talbot.
McDavid increased the lead to 3-1 at 4:08 of the second period, taking a pass from Anton Slepyshev, skating between Kings center Tyler Toffoli and defenseman Derek Forbort, and shooting between Quick's pads.
"It's tough to get down early," Kings coach John Stevens said. "… but at the end of the day you don't want to start against anybody down chasing the game."
Carter cut the lead to 3-2 at 6:19, converting a cross-crease pass from Tobias Rieder.
"It would have been an awesome trip getting this win," Muzzin said. "We had some tough games and a tough back-to-back. [Goalie Jack Campbell] did well in Winnipeg to get us a point [2-1 overtime loss]. We got some points out of this trip (2-1-1) and we're going to have to get some more coming up at home."
