Frequently Asked Questions
Do these pistons fit all 2003-2004 5.9L Cummins trucks?They are intended for 2003-2004 Ram 2500/3500 with the 5.9L ISB common-rail engine. Always confirm your VIN/engine build date and measure your block/bores before ordering.
Are rings included with PDM-3672FCC? Pistons are typically sold without rings so you can match the ring pack and end gaps to your application. See our 5.9L Cummins piston rings.
What compression ratio will I have? Compression depends on bowl design, gasket thickness, deck height, and piston protrusion. Your machine shop should calculate final compression for your exact combo.
Are coatings or valve reliefs required? Requirements vary by camshaft, boost, and intended use. Work with your builder to select coatings and verify valve-to-piston clearance during mock-up.
Do I need head studs with these pistons? Head studs are strongly recommended in any elevated-boost build. See our 5.9L head stud kits.
