Performance Diesel Rebuilds

The Cummins® 5.9L Inline 6 12-Valve Head

The Cummins® Diesel is one of the strongest, most bulletproof engines ever made. But like any engine, the miles will eventually take their toll. We offer 4 different packages to match your budget.

Precision machining with exceptional detail paid to tolerances assures a tighter mechanical seal between valves and valve seat, and fuel delivery efficiencies that exceed those of today's factory engines. This results in more horsepower, more torque, and better fuel economy.

The combination of UCF Machine Shop's skilled machinists and our use of the highest quality parts will give you a stronger, better performing diesel.

Contact us for other available options. We offer a large array of custom options designed to enhance the performance and turn your engine into the ultimate diesel. We can provide new head castings, cores, and more.

We also do performance valve jobs for Ford Power Stroke, and GM DuraMax diesel engines. Contact us today with your questions.
