About this kind of part (general, written by SearchForPart)

Rings on the piston seal the combustion chamber and control oil on the cylinder wall. Blow-by, oil consumption and low compression are the usual signs. Check the ring set, the bore size (standard or oversize) and the piston it fits.

When ordering, give the part number exactly as printed and its maker, and the make, model and year of the truck, trailer, reefer unit or machine (or the engine or unit serial number). SearchForPart shows fitment only as the source printed it: check it before you order.
