It looked like second placed Colls might spoil the party when they took the lead inside two minutes through Michael Dunn, but the Highwaymen weren’t to be denied.
Sean Taylor, Joe Walton and Jack Foalle scored the goals to mark a historic first season in the Northern Premier League in front of 950 fans.
Despite the defeat, Colls remain in second place and are guaranteed of their play-off spot.
The other three spots will be shared across four teams after Cleethorpes Town bowed out of the race with a 2-1 defeat at Sheffield.
Marc Newsham’s 90th minute strike, after Brody Robertson had cancelled out Andrew Gascoigne’s first half penalty, could yet prove crucial in ensuring Sheffield reach the play-offs.
Sheffield remain fifth, level on points with third placed Ossett United and fourth placed Brighouse Town, who won against Marske United and Pickering Town respectively.
The only other team left in the race is Tadcaster Albion, who were 3-1 winners at Frickley Athletic.
At the bottom, it’s looking bleak for Gresley who lost again, 3-0 at home to AFC Mansfield, to remain rooted to the table.
Carlton Town edged a point further away from them thanks to a 1-1 draw with Stocksbridge Park Steels, who are now safe.
Spalding United and Wisbech Town remain down there too following defeats against Loughborough Dynamo and Lincoln United respectively.
