Cycle Pro Chrome Rings

These ring sets have a top compression ring that is chrome plated and lapped for resistance to wear and scuffing, and faster seating. Steel material is used for high strength and excellent fatigue resistance. Intermediate rings are of Torsional twist design. Oil rings are of either circumferential design or Cycle Pro’s® patented channel oil ring, both of which provide quick seating, positive oil control and long life.

Cycle Pro Cast Rings

These ring sets contain compression rings which are manufactured to precision specifications from high grade grey iron castings The top compression rings are black phosphate coated and normally beveled on the inside top, which gives a torsional twist characteristic or relieved on the lower ridge for oil scraping characteristics. The second compression ring is normally a scraper ring commonly used in the second groove. Oil rings are generally 3-piece circumferential style, which provide quick seating, positive oil control and long life.
