Nick Haringman, Adam Levenson and Ben Kaye were the goal men for Raiders.
Faithfold led 2-1 after 80 minutes via a well-worked goal by Zalmi Cohen for the first and an outstanding shot from 30 yards out looping by youngster Gav Lewis.
Relieved Raiders boss Sam Rose told JC Sport: "After a really difficult and inconsistent season for Raiders C, this was an indication of what we can do when we pull together and do the simple things right. We’ve now secured two comeback victories on the bounce.
"After a dreadful first-half performance, the boys rallied in the second half after some honest words at half-time and they got their rewards on the second half.
"Our focus now needs to be on eliminating slow starts and finding some consistency to our game. Only then will we return to being a force to be reckoned with in this division."
