Description
High-Performance Piston Ring Set for Heavy-Duty Engines
The Cummins 4376565 piston ring set is a critical component designed to restore your engine’s peak cylinder functionality and maintain optimal compression. Engineered specifically for heavy-duty applications, this kit provides excellent protection against cylinder wear while ensuring a tight seal to prevent combustion gases from entering the crankcase. This part is also available under the numbers: 2881756, 4309336, 5633496, and 6379407.
This piston ring kit is primarily used on EPA13 15-liter ISX and QSX series engines. By directing intense heat away from the hot piston and into the cooled cylinder wall or engine block, these rings prevent thermal overload and extend the service life of your power cylinder components. Replacing worn rings with this premium set helps eliminate oil consumption issues and restores lost engine power.
