Powerstroke, Duramax and Cummins diesel experts

Diagnostics

Diesel Engine Repair

We specialize in Ram, Ford, Chevrolet and GMC diesel trucks. These trucks require extensive knowledge, special tooling and highly sophisticated computer programs. We use factory diagnostic software which gives us the same access to trouble codes, test modules and programming functions as the dealership. Whether a no start, fuel system contamination, cylinder misfire, DPF and emissions system failure, transmission issue or electrical gremlin we have the resources to accurately diagnose the problem.

Diesel Engine Repair

Diesel Engine Repair

The Powerstroke, Cummins and Duramax engines are complex. They require special tooling, software and knowledge and are not something for a "do it all repair shop". Whether it be an oil leak, cylinder misfire, boost leak or a catastrophic engine failure we have the expertise to diagnose and repair it right the first time.

Maintenance

Maintenance, maintenance, maintenance. We cannot over state the importance of routine maintenance. Fuel filters, crankcase filters, oil changes, differential fluid, transmission and transfer case fluid should all be regularly serviced to ensure the longevity of your truck and prevent the premature failure of expensive critical components. We use only the best filters and fluids approved by Ford, Ram and GM.

Fuel System Contamination

The fuel systems on the Powerstroke, Cummins and Duramax engines are highly sophisticated and operate under extremely tight tolerances. When contaminated with water, gasoline or DEF fluid there is a likelihood of a catastrophic failure of the entire fuel system which can lead to an extremely expensive repair bill. Having a fuel system issue though does not automatically mean you need a complete fuel system replacement. Without the proper diagnostic tools and experience many repair shops will just automatically replace the entire fuel system when it isn't necessary.

Diesel Transmission Repair

If you can dream it, we can build it! Lift kits, wheels and tires, complete restorations, off road trucks, resto mods and installing diesel engines where they were never intended to be. We can custom outfit your work truck with a flat bed, tool boxes, winches, lighting, you name it. We offer a complete line of performance parts and upgrades including head studs, turbo upgrades, FASS and Air Dog lift pumps, up pipes, high flow injectors, CP3 swaps and more. 

Diesel Transmission Repair

Diesel Transmission Repair

The transmission behind your Powerstroke, Cummins or Duramax diesel engine is robust and complex. When problems arise, it doesn't always mean your transmission needs to be replaced. Often times with the proper diagnostics we can save you a lot of money; without throwing expensive, unnecessary parts at your truck like many other places.
