have a set of 6 stock bore 5.9 pistons. These are OEM pistons that I had Crutchfield Machine work. They have been cut down .100 to lower the compression to about 15:1 CR. The cut also allows for the use of a camshaft requiring fly cuts. The bowl has been opened and all edges smoothed which will reduce possible hot spots and piston failure. These were non-reentrant Common Rail pistons. Also all 6 pistons were weighed, then 5 were balanced to match the lightest to +/- 1 gram. Last they were all soda blasted to clean any carbon and further smooth the surface. These are ready to be sent to be coated or installed in a stock bore 5.9. I am also including a brand new set of 6 OEM stock bore rings for these pistons. I was going to use these but decided to go with a 6.7 block and ditched my 5.9 plans*nx*Feel free to message or contact me with any questions. Asking 500.00 shipped in the US. Thanks for looking...Ben 419-203-4443:Cheer:
