Description
When your engine’s losing compression or burning oil, worn piston rings are usually the culprit. You’ll hear it in the way she sounds at startup and see it in the exhaust smoke that follows you around the field. This complete ring set gets your 301 cubic inch six-cylinder gas engine back to sealing tight and running strong, so you can focus on the work instead of worrying about your power plant.
What You’re Getting
- Complete ring set with precise 4-3/16 inch bore sizing for proper cylinder seal
- Three compression rings at 3/32 inch thickness for optimal sealing pressure
- Two oil control rings at 1/4 inch thickness to manage lubrication properly
- One complete set services one cylinder – order six sets for a full engine rebuild
- Quality construction that meets original equipment specifications
Built for Gas Engine Applications
This ring set is specifically designed for 301 CID six-cylinder gas engines with the 4-3/16 inch bore configuration. These engines were workhorses in their day, powering everything from utility tractors to loader applications where steady, reliable power was essential for getting the job done.
Made to Last
These rings are built to handle the heat cycles and combustion pressures that gas engines dish out day after day. The compression rings create the tight seal needed for good power output, while the oil rings keep lubrication where it belongs – not burning up and smoking out your exhaust stack.
Installation Notes
Make sure you’ve got the right application – this set won’t work with block numbers R40940 or R49550. Take your time with ring installation and use a proper ring compressor to avoid breaking them during assembly. A little engine oil on the rings during installation helps them slide into place without damage.
