One Piston ring for 5 HP New Holland farm engine.  This ring fits only the 5 5/8" STD size bore diameter with a 1/2" wide groove.  This is for one  ring only. If you want two you must buy more than one.   You will get a high quality USA made ring.    This will not fit the 4 HP or smaller New Hollands  that have smaller bore diameters.  If your ring grooves are worn wider than 1/2" please contact me before you buy these rings.   If you are not sure if it will fit your engine email me and we will get it right. 
Please check your ring grooves with a 1/2" drill bit for size before ordering.  If a 1/2" drill bit will not stand up in the groove by itself when stuck in the ring lands this means that the grooves are worn and you will need wider custom made rings or spacers.
 I specialize in obsolete and hard to find piston rings for most any application.  

We have piston rings, decals, gasket sets and other parts for the Farmall M, H, Oliver, Case, John Deere, Minneapolis Moline, AC, and other tractors at ringspacers dot c o m.
