When you’re rebuilding that old IH engine and need to go oversize, you want rings that’ll seal properly and last through countless hours of field work. This overbore ring set is sized for a 4-1/8″ cylinder—that’s .125″ over standard bore—and gives you everything needed to restore compression and get your tractor back to pulling strong.
What You’re Getting
- Complete 4-ring set per cylinder: 3 compression rings at 3/32″ and 1 oil control ring at 1/4″
- Sized for 4-1/8″ overbore cylinders to match your machine work
- Quality TISCO construction that handles the heat and pressure of hard work
- Direct replacement design—no modifications needed during installation
Built for Real Farm Work
This ring set fits International Harvester’s 164 CID 4-cylinder engines that powered many of the classic Farmall tractors. Whether you’re restoring a vintage H, M, or similar model that’s been pulling plows and cultivators for decades, these rings will help get that engine back to factory specs.
Made to Last
Rebuilding an engine isn’t something you want to do twice, so these rings are made to handle the temperature swings and constant pressure cycles that come with farm work. The materials and tolerances are designed to maintain proper compression and oil control for thousands of operating hours.
Good to Know
This is sold as one complete ring set for a single cylinder—you’ll need four sets for a complete engine rebuild. Make sure your machine work brings the cylinders to exactly 4-1/8″ for proper ring fit. A good tip: check your cylinder taper and out-of-round measurements before ordering to ensure the overbore size is right for your block.
