Helpful Notes
- Measure cylinder bores with a dial bore gauge; hone with torque plates for final finish.
- Verify ring end-gaps to your power level, fuel, and intended usage.
- For high-lift cams or big valve jobs, consider the fly-cut piston version.
- Always check piston-to-wall clearance against the supplied instructions/specs.
FAQ
Do these pistons include rings?Yes. PDM-360STD ships as a complete set with rings, wrist pins, and clips for all eight cylinders.
Are these drop-in for stock bore?Yes. These are standard-bore (STD) pistons intended for OEM bore size after a proper hone. Always confirm clearances during assembly.
What's the difference between these and the fly-cut version?The fly-cut version adds ~.100" valve reliefs to increase piston-to-valve clearance for high-lift cams. PDM-360STD is the standard crown without fly-cuts.
Will the coatings help with towing heat?Yes. The thermal barrier crown coating helps keep heat in the chamber, and the ceramic skirt coating reduces friction, supporting durability under sustained load.
What power levels are these suited for?They are a durable performance cast option for work/ tow and street builds. For extreme competition power, consider a forged piston upgrade.
