The successful blue-yellow weekend in American Killington was completed on Sunday.
After Sara Hector's giant slalom victory on Saturday, another Swedish podium spot came a day later.
It was 32-year-old Anna Swenn-Larsson's 13th podium in slalom in the World Cup and the first for the season.
For Camille Rast, Switzerland, who took her first World Cup victory, there was nothing to do.
She won with a good half-second margin.
Shared – again
Behind her, Swede Anna Swenn-Larsson and Wendy Holdener, Switzerland, shared second place, 57 hundredths behind.
It was not the first time the two shared a podium spot.
When Anna Swenn-Larsson two years ago took her first World Cup victory in her career, she shared the slalom victory with just Holdener.
Now the Swede was chasing her third, but it was never really close despite a second place after the first run.
Camille Rast was third after the first run, but was superior in the second.
Lena Dürr, Germany, led after the first run, but ultimately finished outside the podium in fourth place.
Sara Hector won the giant slalom on Saturday, but could not repeat her success and finished twelfth.
"Completely crazy"
The 25-year-old Rast took her first World Cup podium in Gurgl last weekend after finishing third in slalom.
On Saturday, she took her first podium in giant slalom, also third, and after Sunday's slalom victory, she leads the overall World Cup.
It's completely crazy with everything that's happening now. I'm really, really happy, but it's just the beginning of the season, so it's about continuing like this, she says in the victory interview in Viaplay's broadcast.
American star Mikaela Shiffrin was missing from the starting field after the violent crash in Saturday's giant slalom, where she was chasing her 100th World Cup victory.
