Make Your Diesel Truck More Powerful and Fuel Efficient with a United Engine and Machine Speed of Air Hyperformance Piston and Ring Kit

The Cummins, Duramax, or Powerstroke diesel in your truck is an engineering marvel. It delivers copious amounts of torque while delivering reasonable fuel economy and low emissions.

But what if we told you that it’s possible to make your diesel even more powerful and fuel efficient with fewer emissions? According to the piston wizards at United Engine and Machine, their Speed of Air Hyperformance Piston and Ring Kits can do just that. The pistons feature patented technology from Speed of Air Engine Technologies, a company that helps make internal combustion engines, from motorcycle V-twins to giant marine diesels, more efficient.

Here's how it works:
The Hyperformance piston crowns have machined dimples and a Cerakote thermal barrier ceramic coating. Together, they create a turbulent boundary layer between the incoming air/fuel mixture and accompanying flame front and the combustion chamber walls. This boundary forces the flame front to get much closer to the cooler combustion chamber and a lean burn condition that greatly improves combustion efficiency.

The benefits are impressive:
• Substantial increases in horsepower and torque
• Increase in fuel economy of up to 20% due to more efficient fuel burning
• Reduced NOx, CO2, and hydrocarbon emissions
• Increased engine life
• Reduced exhaust gas temperatures
• Reduced regen cycles and DEF use
• Less carbon buildup
• Extended oil change intervals
• Less visible exhaust at the tailpipe(s)
• Quieter running

Since high compression engines like diesels exert enormous pressure on the top piston rings, United Engine Machine gave the Hyperformance pistons an iron insert for the rings to ride against. Without the insert, the rings would beat themselves against the pistons’ softer aluminum alloy, eventually destroying both. The pistons also have a Cerakote thermal barrier coating on the skirts to better resist high temperatures up to 1,800 degrees F.

United Engine and Machine Speed of Air Hyperformance Piston Kits come with wrist pins, wrist pin retainers, and a ring set with a gapless secondary ring. They’re available for these engines in standard bore and various overbores:
• 2001-17 GM Duramax 6.6L
• 1994-2003 Ford 7.3L Navistar
• 2004-20 Ford 6.0L, 6.4L, and 6.7L Powerstroke
• 1994-98 Dodge Cummins 5.9L 12-valve
• 1998-2018 Dodge/RAM Cummins 5.9L and 6.7L 24-valve
