Description
When you’re rebuilding that old International Harvester engine and need rings that’ll seal properly and last through seasons of hard work, this TISCO piston ring set has you covered. Nothing’s more frustrating than tearing into an engine rebuild only to find out your compression’s still not right because the rings aren’t sealing properly. This set gives you everything needed for one engine with the correct ring configuration for your 3-1/2 inch bore.

Built for Real Farm Work
This ring set is designed for International Harvester’s 164 cubic inch 4-cylinder engines with the 3-1/2 inch standard bore configuration. These were the workhorses powering many IH tractors through the farming operations of decades past. Whether you’re restoring a family heirloom tractor or getting an old field machine back to productive work, proper piston rings are essential for the compression and power you need.
Made to Last
TISCO builds these rings to handle the temperature cycling, combustion pressures, and daily wear that farm engines face. The ring materials are selected to provide the right balance of sealing performance and durability, while the precise manufacturing ensures they’ll seat properly in your cylinder bores for reliable service.
Installation Notes
Take your time during installation and use proper ring installation tools to avoid breaking the rings. Check your cylinder bore condition and piston ring grooves carefully before assembly – worn grooves or out-of-round bores will cause even good rings to fail prematurely. A good shop manual with the proper ring gap specifications for your specific engine will save you headaches down the road.
