INDUSTRIAL INJECTION PDM-3672CC.020 DODGE PERFORMANCE PISTONS FOR 03-04 CUMMINS .020 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.)

The INDUSTRIAL INJECTION PDM-3672CC.020 DODGE PERFORMANCE PISTONS for 2003-2004 Cummins engines come as a complete solution for enthusiasts seeking to enhance performance while maintaining durability. Crafted for the 5.9L Cummins platform, these pistons are engineered with advanced coatings that elevate their reliability and efficiency under extreme conditions.

Each piston is outfitted with PDM's innovative Ceramic Piston Skirt Coating, which delivers outstanding lubrication and can withstand over 350,000 PSI. This remarkable feature ensures seamless operation even at temperatures soaring past 1600°F, making it ideal for both high-performance and heavy-load applications. The gray finish transforms into a sleek glass-like surface during use, demonstrating both functionality and aesthetics.

For high-performance setups, such as those utilizing nitrous oxide or forced induction, the Thermal Barrier Coating on the piston tops plays a crucial role. It actively works to reduce the part's temperature while maximizing combustion chamber efficiency. This leads to notable increases in torque and horsepower—ideal for serious racers or performance seekers.

Sold in a set of six, these pistons come complete with rings, wrist pins, and clips, making them a straightforward drop-in replacement. The performance design features a .020-inch overbore, chamfered tops to prevent cylinder wall scuffing, and fly-cut valve reliefs for optimal clearance when using high-lift camshafts.

The INDUSTRIAL INJECTION PDM-3672CC.020 DODGE PERFORMANCE PISTONS are a premium choice for those looking to enhance their 03-04 Cummins engines with components engineered for superior performance and reliability, efficiently meeting the demands of high-performance driving.
