Kingsbury said: "I'm four for four, so it's a good start to the season, and it's good because it gives me a chance to pull ahead in overall standings.
"But the best part is that I'm feeling better and better on my skis, which is cool."
Kingsbury's flawless record ensures his points tally in the World Cup discipline standings is a perfect 400, with France's Benjamin Cavet well adrift in second place on 230.
The moguls World Cup action continues next weekend when the field heads to Lake Placid.
