After a goal-less first half, Lance Smith struck for the hosts twenty minutes after the break when his low drive from 20 yards seemed to deceive Matt Gould, but Stourbridge were level on 73 minutes as a good move involving Chris Lait and Liam Molesworth saw Liam Probert's angled shot come back off the woodwork for Benbow to pounce and head home.
And Benbow won the game two minutes from time as he took the ball round the keeper to score after Jack Duggan had won a header from Jake Heath's free kick.
The game saw former Leamington and AFC Telford United midfielder Jon Adams given a run-out by Gary Hackett.
Stourbridge line-up: Gould, Hull (Wedderburn 81), Smikle (Broadhurst 60), Tonks, Duggan, Scarr (Probert 52), Adams (Molesworth 63), Birch (Heath 60), Benbow, Brown, Lait.
