The 26-year-old has been in red-hot form this season and returned to winning ways in the first event of two in Sweden after her first loss in 17 in Japan last month.
One became two in Are as Kearney repeated her efforts in the moguls on Friday in the dual moguls a day later – this time beating Nikola Sudova in the big final.
The World Cup champion now has an impressive 1150 points to her name while in the small final Heather McPhie beat off competition from Miki Ito to claim bronze.
Meanwhile in the men’s dual moguls at the penultimate World Cup of the season Patrick Deneen took just his second win of this campaign to boost his hopes of finishing runner-up.
Deneen downed Jeremy Cota to claim gold in the big final with the gap between him and his American teammate in second overall now just 14 points – 629 playing 615.
World Cup champion Mikael Kingsbury ensured his run of finishing on the podium at every event this season continued as he took bronze, albeit for his worst finish, ahead of Bradley Wilson.
