This listing is for Industrial Injection Piston Kits for 2004.5-2007 5.9L Cummins engines. The specific MPN PDM-3673.040 refers to a set of .040 oversized stock pistons that includes rings, wrist pins, and clips.

Available in Std, .020, .040 sizes. Coated & Chamfered Piston Kit Features: Drop-in replacement, complete with rings, wrist pins, and clips. Available in Std, .020, .040 sizes. These pistons are machined .010 off the top and chamfered, and feature a thermal barrier coating for piston tops and a ceramic piston skirt coating. Fly Cut, Coated & Chamfered Piston Kit Features: Drop-in replacement, complete with rings, wrist pins, and clips. Available in Std, .020, .040 sizes. These pistons are fly cut with .100 valve reliefs and have chamfered tops, a thermal barrier coating for piston tops, and a ceramic piston skirt coating. Fly cutting is a machining process to increase piston-to-valve clearance when using high-lift camshafts. Chamfering helps prevent swelling and scuffing of the cylinder wall. The ceramic skirt coating provides lubrication under high temperatures and loads, while the thermal barrier top coating reduces part temperature and enhances torque/horsepower by retaining heat in the combustion chamber.
