A hat-trick from Rasmus Jonsson earned Helsingborg a 3-1 victory at Trelleborg which took them six points clear at the top of Allsvenskan.
The striker opened his side's account after 11 minutes, adding a second from the penalty spot on the stroke of half-time.
Jonsson then completed his treble nine minutes from time before Kristian Haynes netted a last-minute consolation for Trelleborg.
The win gives Helsingborg some breathing space over nearest challengers Elfsborg, who have a game in hand.
GAIS climbed to third with a 1-0 win at home to Kalmar, Wanderson scoring the only goal after ten minutes.
Orebro beat Djurgarden 2-0 to move into the top six. Paulinho put the visitors in front after 24 minutes with Valdet Rama adding a second five minutes later.
