it is our goal to be the best at what we do. 

In order to do that, we stick to what we know. This gives our customers confidence in our 

experience, skills, and recommendations. read on to learn more about what we work on!

5.9L

The 5.9L Cummins was employed by Dodge in their Ram pickups from 1989 until 2008. The base engine design did not change, but the overall performance of the engine evolved throughout the years.



Common repairs include:

  • Gear case re-seal
  • Fuel injector replacement
  • Water pump
  • Cylinder head gasket replacement


We offer full services on all 5.9L Cummins engines.

6.7L

In 2008, Cummins introduced the 6.7L engine to comply with emissions regulations. The “tried and true” inline six design was preserved, but now with more displacement, a new fuel system, and a new VGT turbocharger design. This base engine platform is still used in new trucks to this day, although the 19+ Ram’s have the optional High Output engine which has some fundamental differences.


Common repairs include:

  • Turbocharger replacement
  • Fuel injector replacement
  • Emission system failures
  • Transmission replacement


We offer full services on all 6.7L Cummins engines.

We do not rebuild automatic or manual transmissions; we perform the R&R, and sublet the rebuild to another supplier. We will perform transmission services and limited diagnostics, but will not perform repairs that go beyond the valve body. 

Engine Rebuilding

We do not rebuild engines. We will perform R&R, and purchase remanufactured long block and running complete engines from suppliers that offer a warranty.

Fabrication

We do not provide custom fabrication services unless they are required to complete a repair that we otherwise would provide; this must be handled on a case-by-case basis and is billed by time and materials.
