INDUSTRIAL INJECTION PDM-3672CC.040 DODGE PERFORMANCE PISTONS FOR 03-04 CUMMINS .040 OVER

PDM's Ceramic Piston Skirt Coating, is designed to be used, on any rigid or semi rigid surface experiencing sliding, rotating or oscillating friction. This coating will carry loads in excess of 350,000 PSI as well as lubricate at temperatures in excess of 1600f.

This coating combines the durability of a ceramic resin with the lubricity of the ceramic lubricant. It is used in applications where high temperatures, high loads and high speeds are experienced.

When higher temperatures, than most other types of coatings can provide protection at, are experienced, this coating is fully capable of carrying the load. Gray in color it acquires a glass like finish in use. Cured film thickness of .001 or less requires no change is piston clearance.

PDM's Thermal Barrier Coating for piston tops is designed for Performance engines running; Nitrous oxide, supercharged or Turbocharged. It creates a hard surface specifically designed for engines running High volumes of fuel and/or high compression ratios.

The thermal barrier coating. Reduces part temperature. Keeps heat in combustion chamber longer through the power stroke. Increase torque, H.P. and improved combustion chamber efficiency.

Fly cutting is a machining Process we use to add Piston to valve Clearance, when using High lift camshaft.

Chamfering:

Our performance and race Cummins pistons are Chamfered (The top is tapered to help avoid swelling and Scuffing the Cylinder Wall.)

Designed specifically for enthusiasts and professionals, the INDUSTRIAL INJECTION PDM-3672CC.040 DODGE PERFORMANCE PISTONS elevate the performance capabilities of the 2003-2004 Cummins 5.9L engines. These pistons come in a set of six and are engineered for enhanced durability and efficiency during high-load operations.

Featuring PDM's advanced Ceramic Piston Skirt Coating, these pistons withstand extraordinary conditions, capable of bearing loads over 350,000 PSI and enduring temperatures exceeding 1600°F. This remarkable coating pairs the robust strength of ceramic resin with superior lubricant properties, ensuring a low-friction surface suitable for rapid movement and oscillation. The gray finish not only provides an aesthetic appeal but also develops a glass-like surface with use, enhancing the longevity of the pistons without requiring any adjustments to piston clearance, thanks to a minimal cured thickness of .001 or less.

The Thermal Barrier Coating applied to the piston tops is a game-changer for performance engines utilizing nitrous oxide, supercharging, or turbocharging. This hard surface treatment reduces heat transfer, maintaining combustion chamber temperatures longer to maximize power strokes, ultimately leading to increased torque, horsepower, and improved chamber efficiency.

These pistons are truly a drop-in replacement, coming fully equipped with rings, wrist pins, and clips. The performance enhancements include a .040-inch overbore and chamfered tops that help prevent cylinder wall scuffing and swelling, particularly beneficial when utilizing high-lift camshafts. This meticulous engineering ensures that whether for racing or heavy-duty applications, the PDM-3672CC pistons will excel, strategically balancing performance and reliability for any demanding driving condition.
