Sinister Diesel Fun Fact: 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 spirit perfectly.
More Trivia: United States Patent and Trademark Office (USPTO) has issued Sinister a registration certificate for the color blue for all aftermarket diesel performance truck parts. The trademark applies only to components for resale and does not apply to customization that truck owners make for personal use. So if it is BLUE on a truck as an after-market part it "Should be" Sinister! Who knew.
