Chrome Moly Piston Rings

The face of the top rings in these sets are electroplated with chromium to provide a surface.

Chrome moly piston rings.

A great way to take full advantage of the 21st century engineering that goes into piston rings is optimize the break in ring seating procedure. Recommended for all racing applications where file fitting the ring end gap will deliver maximum power. According to joe moriarty of tse racing engines greenland nh about the only applications. When asked if he wants a piston ring set with moly chrome or cast iron faced top compression rings the mechanic often returns the question to the jobber salesman by saying what should i use there is some confusion in the trade as to what type ring set should be used.

Cast iron by nature is very brittle and therefore not as strong as gas. This goes way beyond just choosing the right break in oil although that s an excellent start. The first is carbon s teel which is a much more malleable material than cast iron is able to handle higher temperatures without losing temper and is better able to withstand bouts with detonation. Moly this ring set is highly resistant to scuffing.

As we ll see the process is somewhat specific and less than rewarding if you screw it up. Prior to the advent of moly chrome plated top rings enjoyed widespread use in high performance engines. At hastings we manufacture a bold and broad offering of piston rings one that spans thousands of applications for virtually any engine. The current je piston catalog lists a multitude of ring materials which may appear at first to be a daunting challenge.
