The boys are back! “Sons of Anarchy” will be returning to FX in September for its highly anticipated Season 7 premiere. And if the long wait to getting your fill on Samcro-shenanigans is bumming you out, then this news will certainly get your engine revving.

The cast and crew of the Kurt Sutter drama have taken to social media to give fans a first look at the final season of “SoA” – and we have to admit, it’s a bit chilling. But hey, what else do you expect from a series that has had more gory moments than all the “Saw” movies combined? We still can’t get the noise of Gemma’s carving fork crunching into Tara’s skull out of our head.

From Samcro-selfies to images of deadly props, the motorcycle-riding ruffians made sure to leave no stone – or should we say no skull – unturned as they posted photos to their Twitter accounts. Who knew the Sons were social-media savvy?

Check out the behind-the-scenes photos below that will get your heart racing for Season 7 of “Sons of Anarchy”:
