INDUSTRIAL INJECTION PDM-3354.020 DODGE PISTONS FOR 1998.5-2002 CUMMINS STOCK .020 OVER

1998.5-2002 24v Cummins Stock Pistons .020 Oversized. 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-3354.020 Dodge Pistons are specifically engineered for 1998.5-2002 Cummins engines, offering a .020 oversized option that enhances performance for both stock and aftermarket applications. These pistons are precision-crafted to meet the demands of high-performance diesel engines, delivering reliability and efficiency where it matters most.

Featuring PDM's innovative Ceramic Piston Skirt Coating, these pistons excel in environments with sliding, rotating, and oscillating friction. This advanced coating can handle loads exceeding 350,000 PSI, while also providing lubrication at temperatures beyond 1600°F. This combination of ceramic resin durability and ceramic lubricity ensures that the pistons maintain optimal performance even under extreme conditions.

The thermal barrier coating applied to the piston tops is particularly beneficial for performance engines that utilize nitrous oxide, supercharging, or turbocharging. By keeping heat within the combustion chamber for more extended periods, this coating enhances torque and horsepower while improving overall combustion chamber efficiency.

Every set of PDM pistons is designed as a drop-in replacement that includes rings, wrist pins, and clips, ensuring a straightforward installation. Stock options provide reliable power, whereas performance variants come equipped with chamfered tops to minimize swelling and scuffing against the cylinder wall. For race enthusiasts, the fly-cut feature with .100 valve reliefs adds essential clearance when using high lift camshafts.

Our INDUSTRIAL INJECTION Dodge Pistons represent an optimal solution for any 5.9L Cummins owner looking to enhance performance and reliability. Whether used in daily driving or racing conditions, these pistons are engineered to deliver unmatched durability and efficiency in the toughest scenarios.
