they are the same bore as the 12v but the rings are different, i cant remember if theres more or if there is a different spacing. cummins pistons are good, IMO getting them coated is really for pretty high performance applications from my understanding

Shouldnt have an issue using the newer syle pistons, Its one of the few minor things that change for application and years, the block is the same.

I would also suggest using pistons from cummins, as far as coating goes, i wouldnt be too concerned about it. The OEM pistons last forever as it is. Also, cummins alos sells different grade of pistons (gade a/b/c), not too sure what the differences are though...

2nd gen piston kits (std bore)

3802561 grade a
3802562 grade b
3802563 grade c

They also have .5 and 1mm oversize available

The Grading has to do with piston protrusion above the surface of the block..... It's covered in the service manual....... I'm told that it's really not all that necessary...... It's only the automotive apps that do that anyway....
