They've knocked off their southside bogey team and it's given Tuggeranong belief they could just end another hoodoo.
The Bushrangers beat the Woden Valley Rams 28-6 at Phillip on Saturday, ending a four-game losing streak against their southern rivals which included last year's Canberra Raiders Cup grand final.
But there's a big drought still running for ladder-leading Tuggeranong, who remain three points clear at the top of the table.
They're yet to win a premiership and came agonisingly close when they lost to the Rams in last year's decider.
Bushrangers coach Jarrad Teka was delighted with the effort and said it gave them confidence in the run-in to the finals.
"It's a good sign for us mentally to get up over Woden because it's the first time in five games we've beaten them," Teka said.
"Now that mental block is gone we've got the belief that we can win having beaten the champions last year.
"But that's still a long way away, that's still a long road to there, we've got four quality teams in front of us.
"They've had the wood over us the last couple of years ... they're definitely our bogey team."
The Bushrangers scored the opening two tries of the game, including one of two long-range efforts.
Tuggeranong five-eighth Wezley Alexander opened the scoring with a great run before fullback Ngarima Low ran 90 metres to score off the back of a scrum.
The Rams got their sole joy of the afternoon when Mitchel Souter darted out of dummy half, before Bushrangers winger Connor Massen went tryline to tryline after swooping on a grubber kick.
Tuggeranong completed the victory with second-half tries to Jarrad Kennedy and Michael Brophy.
The Rams lost Brayden Robertson to a dislocated shoulder that he needed to go to hospital for.
"Losing Braydo early at six wasn't great. We've got a few busted, but if we want to be contenders again this year we've got to be working our butts off for the next four weeks and see what happens," Rams coach Lincoln Withers said.
Belconnen thumped Yass 38-0 at Yass, while the Queanbeyan Blues beat Gungahlin 30-16 to climb into second.
