    What do you get when a group of diesel, truck and 4x4 off-road enthusiasts get together with a dream of changing the automotive aftermarket industry? You get Sinister Diesel. Founders Brian George, Michael Mitchell and their whole team share a love of everything diesel. One afternoon, while working on Brian’s truck they thought of starting a new company. Sinister Diesel® actually started out as MKM Customs. So, why the switch to the Sinister name? It appeals to Brian and Mike because they feel it captures the spirit of the diesel lifestyle. “The spirit of diesel truckers is like our own,” Brian says. “A little bit rebel. Of course, we don’t all live a rebel lifestyle, but we all share that spirit. The name Sinister captures that sprit perfectly.”
