  • CNC-controlled gap chamfer — improves compression retention and reduces combustion gas leakage
  • Reverse-twist intermediate rings — enhance groove side sealing for superior oil control
  • CP-20 oil ring assemblies — feature a 20° ear angle for optimal cylinder wall sealing and improved oil drain-back
  • OEM-matched specifications — meets or exceeds original equipment standards
