INDUSTRIAL INJECTION PDM-3672.020 DODGE PISTONS FOR 03-04 CUMMINS STOCK .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 Cut (valve relief): .100

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-3672.020 DODGE PISTONS for 03-04 Cummins Stock .020 Over are engineered for high-performance applications, providing exceptional durability and efficiency for enthusiasts and professionals alike. These ceramic-coated pistons are specifically designed to withstand extreme conditions, making them the ideal choice for those running heavy loads and high speeds.

Featuring PDM's advanced Ceramic Piston Skirt Coating, each piston is built to handle friction with a load capacity exceeding 350,000 PSI while maintaining lubricity at temperatures over 1600°F. This unique coating yields a glass-like finish that requires a minimal cured film thickness of just .001, ensuring no alteration in piston clearance is needed.

For high-performance engines, these pistons come equipped with a Thermal Barrier Coating on the tops, ideal for setups using nitrous oxide, supercharging, or turbocharging. This hard surface retention reduces part temperatures, allowing engines to sustain higher compression ratios and fuel volumes while improving torque and horsepower.

Sold in a set of six, these pistons come fully equipped with rings, wrist pins, and clips, making installation straightforward as a drop-in replacement. With a .020-inch overbore, they also feature chamfered tops to prevent cylinder wall scuffing and promote longevity.

For racing applications, a fly-cut machining process provides .100 valve reliefs, adjusting for high-lift camshafts while maintaining vital piston-to-valve clearance.

The INDUSTRIAL INJECTION PDM-3672.020 DODGE PISTONS represent the pinnacle of engineering for 2003-2004 5.9L Cummins engines, merging performance with reliability and ensuring optimal operation in the most demanding environments. Upgrade your engine's capabilities with pistons designed to enhance performance and efficiency for any enthusiast.
