FAQ
Are these pistons coated or fly-cut?No—PDM-3732 are stock-type cast pistons for standard bore. If you want coatings or valve reliefs, see our coated or fly-cut 6.7L piston options in the Pistons & Rings category.
What comes in the box?A matched set of six pistons with rings, wrist pins, and clips for a complete standard-bore rebuild.
Will these fit both early (07.5–12) and late (13–18) 6.7L?Yes—these are specified for 2007.5–2018 6.7L Cummins ISB trucks. Always confirm bowl style and piston protrusion per your exact year and head gasket thickness.
What supporting mods do you recommend?Head studs, quality head set, and fresh bearings are smart while you’re in the short block. Consider injector refresh or OE-plus S&S TorqueMaster injectors for like-new performance.
