4.040+5, 5/64-5/64-3/16 Performance Ring Set
Superior oil control. Improved combustion gas management. Improved top ring stability. Improved sealing. It takes three carefully matched rings to create a Perfect Circle seal. The second compression ring, however play a particularly critical role in controlling oil and combustion gases. The unique Perfect circle profile provides two clear advantages over all other shapes. Prevents top ring float (horsepower loss) and provides maximum oil control. 8 cylinder sets unless noted.
