Storvreta finished top of the regular season standings, just three points clear of Falun, and the pair showed their class again during the Playoffs.
4-0 and 4-1 in their best-of-seven series against Nykvarns and Pixbo earned Storvreta a place in the Final, while Falun survived a tricky Quarter-Final - 4-3 against Mullsjo - before seeing off Vaxjo Vipers 4-1 in the Semi-Finals.
Those victories set up a winner-takes-all clash over 60 minutes in front of over 12,000 fans in Stockholm on Saturday.
In an even contest, it took 37 minutes for the first goal to arrive, Emil Ruud was on hand to pick up a loose ball and steer past the goalkeeper.
But the setback at the end of the second period had little affect on Storvreta, in fact it galvanised them, scoring three times to turn the match on its head.
Hampus Nydenfeldt grabbed the equaliser in the seventh minute, before Gabriel Kohonen - son of Storvreta head coach Mika Kohonen - put the Uppsala side in front from a tight angle inside the final six minutes.
The win was all but sealed in the final minutes, when Sakarius Ulriksson finished off a counter attack, taking advantage of Falun throwing men forward in desperate search of an equaliser.
The side from Dalarna made it 3-2 a matter of seconds later through Emil Johansson, but it was too little too late and Storvreta's party could begin.
It's the second time Storvreta have picked up a hattrick of titles, with this trio coming immediately after Falun did the same between 2020-2022.
The pair have also won every Superligan title since 2010.
