Sub Zero Diesel Performance is your premier automotive and diesel repair shop serving the Bismarck and Mandan area in North Dakota. We offer full OEM replacement parts to keep your vehicle running at its absolute best year round. On top of the great quality offered by OEM replacement parts we have access to thousands of aftermarket products to fully customize any vehicle. We work closely with a top of the line machine shop that allows us to offer fully balanced and blue printed motors for daily driving or competition use. We back these with up to a 5 year 100,000 mile warranty depending on application.
We offer full module programming for all makes and models of vehicles that allow us to be a one stop service for changing IQA codes, TCM, ECM, PCM programming and full valve body setup for transmission repairs. These need to be done accurately every time to keep the reliability of your vehicle at its highest.
Sub Zero Diesel Performance also houses the newest line of Hot Flush machines for routine transmission service or to be paired with a full transmission overhaul. All in house transmission builds require either a new transmission cooler or hot flush service performed by us to maintain full warranty. Our in house transmission builds are custom made for each customers needs. Builds can be anything from a stock rebuild or a full billet build to handle even the most severe use.
