Features & Benefits

  • High-temp alloy piston construction handles intense cylinder heat without losing its shape
  • Coated piston rings provide a low-friction seal to maintain maximum engine compression
  • Restores fuel efficiency by preventing pressurized combustion gases from escaping the cylinder
  • Extends engine service life by reducing the internal friction that causes heat and wear

PAI Engine Piston and Ring Kit

The PAI Engine Piston and Ring Kit provides the core internal strength needed to restore compression in Cummins L10, M11, and ISM series engines. This verified kit includes the piston body and a matched set of high-tension rings to create a perfect seal within the cylinder liner. The piston itself is cast from high-temp alloys to handle the intense heat of heavy-duty diesel combustion, while the rings feature a specialized coating to resist the friction that causes premature engine wear. Replacing worn internal components with this coordinated PAI 111439 set eliminates the blow-by that kills fuel mileage and brings the engine’s horsepower back to its original factory rating.
