Here's a pic of the new piston




Went with the FP diesel cause they are new rather than reman and have a ceramic coating which I really like.

Cylinders going in today!

there not ceramic coated , there phosphate and grafal coated , reduses friction , if memory serves me right mahal has been a oem pistion manufacture for cat cummins jd an others , that is there monanotherm one piece forged steel pistion , why they ever tryed a 2 piece pistion is beyond me .

My understanding is the entire piston is coated like you stated but mine were ordered with a optional ceramic coating which i believe is the off color part you see on the skirt.

in racing they use ceramic as a thermal barrier and only coat the top the piston , i would thing that what u have , top only , ceramic when it brakes down is gritty glass like , u deffinetely would not want that on u cylinder walls going down and getting into your oil ,
be like ceramic plunder only over a longer period , i would bet its just the top or just the bowl that's ceramic coated , swain tech has been doing that for a long time , i haven't kept
up on it , i just know it was more for racing and extreme applications , not general use
