Matty Stevens scored twice in as many minutes deep into the second half to seal victory for AFC Wimbledon at Barrow.
It was only the second win on the road all season for Wimbledon and moves them up to 10th in League Two.
Joe Pigott put the visitors in front after two minutes before Andy Dallas equalised just before half-time.
But Stevens found the net after 76 and 77 minutes, for his ninth and 10th goals of the season to seal the victory for Johnnie Jackson's side.
The result means they jump above their opponents, who have now not won any of their last six league games.
The visitors, who had to do without midfielder Myles Hippolyte and striker Omar Bugiel who were away on international duty with Grenada and Lebanon respectively, were gifted an early goal.
Pigott profited from a poor back header from Bluebirds skipper Niall Canavan to turn the ball past Paul Farman from close range after James Tilley’s initial shot had been shovelled out by the goalkeeper.
Tilley forced a terrific save from Farman from 25 yards before seeing an in-swinging corner go straight in, only for the goal to be disallowed for a foul in the area.
It was a goalkeeping error which let the home side back in it just before the interval as Owen Goodman underhit his goal-kick which was chested forward by Dallas, who held off his marker and finished confidently from the edge of the box.
The game could have gone either way in the second half with both goalkeepers making saves before Stevens stepped up.
His first goal saw him poke the ball beyond Farman after Pigott had flicked on and before Barrow could reset, the ex-Forest Green Rovers man added another from close range after good work from Josh Neufville.
A first away win since August was a timely boost and with three games in hand on some of the teams above them, the Dons will hope to move further up the table when they host Accrington Stanley on Tuesday night.
Barrow boss Stephen Clemence:
"It’s so frustrating. We have to keep going. The only thing you can do when you are in these sort of runs is to stick together and keep working hard.
"The boys deserve more points than we have picked up in the last five or six weeks. For whatever reason, it hasn’t gone our way."
AFC Wimbledon manager Johnnie Jackson:
"It was a close game and it was in the balance for quite a while. It's a tough place to come and they were tough conditions today so it was never going to be too pretty.
"But in a tight game, we had the moments of quality in the second half to take the game away from them, so it was a really good away performance."
