The gang from Ängelholm topped the table before the hot meeting in Catena arena.
The home team also got off to a great start when Adam Tambellini put 1-0 after 2.18 - assisted by points king Daniel Zaar who scored his 99th point in Rögletröjan at SHL level.
But Frölunda came back.
Max Friberg equalized with four minutes left of the first period and at the beginning of the second Nicklas Lasu scored 2-1 to the guests.
"Tearing them apart"
Frölunda's coach Roger Rönnberg was both satisfied and wanted more before the last period.
- I think we break Rögle's passing game well, then in the attacking game we do not really get to the goal and create these hottest situations.
I would like to turn that up a bit, Rönnberg told C More during the period break.
Frölunda lacked, among other things, suspended captain Joel Lundqvist, but still managed to hold off and take his third straight victory.
Took out the goalkeeper
Rögle took out goalkeeper Christoffer Rifalk with two minutes left in search of a draw, but in vain.
Instead, Frölunda put 3-1 in an empty cage.
The Gothenburg team thus takes over the league lead in the SHL.
- We came here to work and we did.
No one fell out of the frame and we had patience in every change.
Overall, we do a lot of good things, says Frölunda's Nicklas Lasu.
Rögle went on his third straight home loss.
