Replacement piston rings designed to restore compression sealing and precise oil control. 🔧

  • Includes top compression rings, second compression rings, and oil control rings.
  • Top compression rings are barrel face for improved sealing and ring stability.
  • Second compression rings are Napier; reverse twist with a taper‑machined face duplicates the OD bottom‑side scraping edge of a positive twist torsional ring.
  • Oil control rings are three‑piece Flex Vent; four steel rails and two expanders provide uniform pressure and positive oil control.
  • Three‑piece design allows rails with a small cross section for better conformability to the bore and improved oil economy.
  • Helps transfer heat between the piston and cylinder wall and controls combustion gases to transfer energy to the crankshaft.

Includes enough rings for two pistons (unless noted). Made in the USA. 🛠️🇺🇸
