When you’re rebuilding that trusty Massey engine and upgrading to overbore pistons, having the right rings is what makes or breaks the job. This set includes everything you need to ring four pistons with the proper sealing and oil control for a 3-5/16″ overbore setup. You get the compression rings that handle the power and the oil control rings that keep everything running clean—exactly what you need for a professional rebuild.
What You’re Getting
- Complete set for 4 pistons with proper ring configuration for overbore applications
- Two 3/32″ compression rings and two 5/32″ rings per cylinder for optimal sealing
- TISCO quality construction that handles the increased stresses of overbored engines
- Precision-sized for 3-5/16″ bore diameter Super Power pistons
Built for Real Farm Work
This ring set is designed for Massey Ferguson engines that have been overbored as part of a performance rebuild. When you’re increasing the bore size, you’re getting more displacement and power, but that also means higher cylinder pressures and more heat. These rings are engineered to handle those increased demands while maintaining proper compression and oil control through long operating hours.
Made to Last
TISCO builds their piston rings to handle the harsh conditions inside diesel engines – high compression ratios, constant heat cycling, and the contaminants that come with farm work. These rings are manufactured to maintain proper tension and sealing through thousands of operating hours. The materials and design account for the thermal expansion that comes with overbore applications.
Installation Notes
Make sure your cylinder walls are properly finished and within spec before installing these rings. Take your time with ring gap measurements—overbore engines need precise clearances to run right. If you’re not experienced with engine rebuilds, this is definitely a job for someone who knows what they’re doing, as proper ring installation is critical for long-term reliability.
