What could you get when a team of diesel, truck, and 4x4 off-road fans get together, while being united by a dream of radically changing the automotive aftermarket? You could surely get Sinister Diesel! The company’s founders, Michael Mitchell and Brian George, just like each and every one of the members of their team, share a love of everything diesel. And so it happened that one afternoon, while having to work on Brian’s truck, they’ve started a new company.
Now customers can easily find one of the greatest selections of high-quality Sinister Diesel performance products all in one place. The company has become a one-stop shop for Duramax, Cummins, and Powerstroke diesel performance parts for many off-road enthusiasts. Sinister Diesel had their own vision about exactly how their products should perform and look like. Some of the company’s products feature distinctive and stylish metallic blue color, that the company itself calls the “Sinister Blue”.
Right from the very beginning, Sinister Diesel has gotten a great reputation for their products; that’s how the company knew that they were on the right track. Today, it is perhaps one of the fastest developing companies providing high-performance aftermarket diesel components and systems. The brand is proud to offer air intakes and parts, injectors, Sinister EGR delete kits, tuners and programmers, Sinister Diesel exhaust systems, etc. The company offers high-performance aftermarket parts for any type of diesel trucking to help their customers modify or repair the Duramax, Cummins, or Powerstroke diesel engine. The spirit of diesel trucking fans is very much like their own - a little bit rebel. We don’t all lead rebel lifestyles, but we all can share that spirit, and Sinister Diesel captures it.
