Product Details

The Sealed Power E-458K 20 is a premium engine piston ring set manufactured to meet the rigorous demands of modern internal combustion engines. The "20" suffix denotes a 0.020-inch oversize, making this set designed for engines that have been bored 0.020" over standard to restore proper cylinder wall clearances during a rebuild.

Sealed Power produces these rings using ISO and QS certified manufacturing processes, ensuring consistent quality and dimensional accuracy across every set. The result is a ring set built to perform reliably from the first startup and over the long term.

Key Features:

  • Plasma-Moly coated top compression ring for reduced friction, enhanced wear resistance, and improved sealing against the cylinder wall
  • 0.020" oversize sizing for use in engines bored 20 thousandths over standard
  • ISO & QS certified manufacturing for consistent dimensional precision and quality control
  • Leading-edge materials selected to withstand the heat, pressure, and mechanical stress of modern engines
  • Designed as a direct-fit replacement to restore compression and oil control during engine overhaul
  • Complete ring set included for all cylinders in the application

Sealed Power is a trusted name in engine rebuilding, offering application-engineered internal replacement components that meet or exceed OEM specifications. The E-458K 20 piston ring set is an ideal choice for engine builders and mechanics performing a professional-grade overhaul or rebuild.
