Is the price for one piston or a full engine set?
At CPP Diesel, the listed price is for a set of 6.
What bore size do I need?
.020" over typically corresponds to ~4.035" bore. Always verify with your machine shop after measuring cylinder wear and finish.
Are rings included and pre-installed?

Do I need HO-specific pistons?
Yes. 2001–2002 HO engines (VIN “7”) use different pistons than SO engines—use this HO-specific part number.
