FAQ
Do these include rings and pins?Yes. This PDM-3673.040 set ships with matched rings, wrist pins, and clips for all six cylinders.
Are these forged or cast?They are OE-style cast pistons designed for stock rebuilds and daily-driven reliability.
Will they work with my 2004 (early) truck?These fit 2004.5-2007 common-rail 5.9L engines. Early-2004 ('03-early '04) applications use different pistons.
What else should I replace during the job?We strongly recommend new head studs, a full upper/lower gasket set, and to measure for the correct MLS head gasket thickness.
