FAQ
Do these come with rings and pins?Yes. This kit includes matched rings, wrist pins, and clips for all six cylinders.
Are these true “drop-in” pistons?They are designed as direct-fit for the 5.9L 12V, but proper machining to .040" over and measurement of clearances is required.
Will these work for towing and mild performance?Yes—pair with quality head sealing (gasket + studs) and appropriate fueling/air setup for the intended use.
What if my block cleans up at .020" or .030"?Order pistons that match your machinist’s final bore recommendation. This listing is specifically for .040" over.
