Replacement piston rings designed to restore compression and oil control for two pistons. Includes top compression rings, second compression rings, and three-piece oil control rings for consistent performance. 🔧
- Top compression rings are barrel face for improved sealing and heat transfer
- Second compression rings are Napier-style reverse twist with a taper-machined face to duplicate the OD bottom-side scraping edge of a positive twist torsional ring
- Oil control rings are three-piece flex vent; two rails plus expanders provide positive oil control
- Three-piece design allows rails to be manufactured with a small cross-sectional area for better conformability to the bore
- Promotes side sealing to prevent oil from being forced under and behind the ring for better oil economy
- Helps transfer heat between the piston and cylinder wall and controls combustion gases so the piston can transfer energy to the crankshaft
- Made in the USA. Includes enough rings for two pistons unless noted; two rings per groove except for rails, which use two rail rings per expander.
