This .040 inch oversize piston is designed for worn cylinder bores that need to be rebored to bring your engine back to life. It’s the same quality replacement you’d get in a complete rebuild kit, available individually when you just need this one piece.
What You’re Getting

- Exact replacement design that fits like the original factory part

Built for Real Farm Work
This piston fits various International Harvester tractor engines that have been rebored .040 inch oversize. These are the same engines that power utility tractors, row-crop machines, and other IH equipment that’s been putting in years of honest farm work. Whether you’re doing your own engine work or having it done at the shop, this is the quality part that’ll get you back in the field.
Made to Last
International Harvester built engines to run hard and long, and this replacement piston maintains that same standard. The alloy construction handles heat cycles and compression loads just like the original, so you can expect the same reliable service life you got from your factory piston when it was new.
Good to Know
Remember that using an oversize piston requires machine work—your cylinders need to be bored .040 inch over and honed to the proper finish. Most engine shops can handle this work, and they’ll want to check piston-to-wall clearance to make sure everything’s within spec. Don’t forget to order the matching ring set when you’re planning your rebuild.
