You and your vehicle are the reason we are here, without you we would not be in business. We depend on you our customer to trust us so much that you will return and refer your friends & family. Without this trust we would go out of business. We value your respect and trust more than we desire making money.


  1. Never sell a service or repair that is not needed. The majority of repair shops will try to sell you some type of B.S. service that is not needed and does nothing but make them extra money. For example : diesel fuel injector flushes
  2. Never charge a customer for parts or labor for a repair if our diagnosis is wrong, we will simply reinstall original parts with no labor charges to the customer. Our customers never have to pay for our mistakes unlike most dealerships.
  3. Send our customers to the dealership if the repair will be covered under the factory warranty. We know that most light duty diesels vehicles come with a factory 5 years / 100,000 mile power-train warranty. Why should you pay us for a repair? When you can get it done for free, this is just another example of how we earn your trust.



We perform all regular scheduled maintenance, such as Oil changes / Fuel Filter(s) / Transmission fluid changes / Front & Rear differential fluid changes / Power Steering fluid flush / Serpentine belt replacement. Maintenance in the long run is cheaper than repairs and is crucial to a long healthy life of your vehicle. If you neglect to perform routine maintenance you are asking for trouble. The transmission service is the most overlooked service or the one put off the most because it is a little pricey @$200 to $300 every 30k to 50k miles but compared to the cost of replacing it @ $3000 to $5000 the service does not seem so bad. You should follow the scheduled routine maintenance intervals according to your owner’s manual.


We specialize in diagnosing and repairing Ford Power Strokes, Dodge Cummins and Chevy Duramax light duty diesel trucks. If your vehicle has drivability or performance related issues or you are just in need of regular maintenance or service we are the most qualified and experienced light duty diesel repair facility in Colorado. We also provide diesel emission testing.


We sell and install performance products and accessories. Such as exhaust systems / Tuners – Modules / Air Intake systems / Turbos.
