Goals from Loic Remy, Andros Townsend and Jermaine Jenas, all of whom joined the club in the last transfer window, helped Harry Redknapp's men to a vital 3-1 victory against Sunderland.
And the R's first team coach says the trio, as well as Christopher Samba, have played a major role in the Hoops achieving back-to-back wins for the first time in the Premier League since December 1995.
Jordan told the club website: "Chris has come in and been exceptional. It's no surprise his performances keep improving. He just needed games.
"He's got the games under his belt now and is getting better and better. He gives us a voice in the dressing room as well which is vital for us. He's a leader.
"The two lads from Spurs have also been great for us. Jermaine has come in and his experience is key. He's not only a very good player, but he has a good head on him and is a great person to have about the club. His goal was fantastic.
"Along with Andros, who is just starting his career, they've been fantastic for us. Andros is playing with a maturity that you just don't expect from one so young. He's expressed himself fantastically well.
"Loic will always get you goals. He's a fine finisher and has already shown why we were so keen to bring him to the club in January."
Like Redknapp, Jordan believes one or two clubs are now beginning to look over their shoulders, with the business end of the season fast approaching.
"Harry has always made the point that he has a great belief in what we are trying to achieve here - to get ourselves out of a very difficult situation," said Jordan.
"There's still a very long way to go in that respect, but what we have done is given ourselves a chance with a few good performances and results. There's a bit of belief around the place now. That's a major thing."
