Black Smoke Mafia is a grassroots company based out of Northern California. We are a brand of brothers that came together to sell products to our fellow diesel truck enthusiasts. We currently have T-shirts, tank tops, sweatshirts, hats, and a large variety of custom designed stickers for sale. We host Northern California's largest all truck event called Truck Mania as well as Golden State Diesel Fest. Follow us on Instagram and Facebook to keep up with upcoming events and new products for sale.
