RINGS 3 5/8 STD

Includes top compression rings, second compression rings, and oil control rings

Top Compression Rings are Barrel Face

Helps in the the heat transfer process between the piston and cylinder wall

Controls combustion chamber gases allowing the piston to transfer the energy of the expanding combustion gases, to the crankshaft

Second Compression Ring are Reverse Torsional Taper Face

Promotes side sealing that prevents oil from being forced under and behind the ring resulting in better oil economy

Reverse twist ring along with a taper-machined ring face duplicates the OD bottom side scraping edge of a positive twist torsional ring

Oil Control Rings are Three Piece Flex Vent

Three-piece design allows rails to be manufactured with a small cross sectional area for better conformability to bore

Provides uniform pressure through four steel rails and two expanders assuring positive oil control

Made in the USA
