DURA-MOLY(TM) FILE FIT RING SETS - Continuing into the New Millennium, Childs & Albert has developed a ring technology for both racing and general performance. Knowledge gained over the last 25 years of ring manufacturing has led to the development of two new piston rings. For the ultimate in plasma moly rings Childs & Albert has developed the new Dura-Moly (TM) compression ring. Simply stated it is the best moly ring money can buy, bar none! Available in 1/16, .043, .017, .031. 5/64 cross sections.
The Childs & Albert Dura-Moly (TM) Ring is a newly designed ring, not just another re-hash of old technology. Unlike other conventional moly types the Dura-Moly(TM) Ring, made from premium ductile iron, is precision finished over the entire outside surface before the moly is applied. Additionally, the moly is applied (plasma process) at a much higher impact rate than normal. This high density plasma process virtually eliminates the fracturing and flaking common with other types. The net result is 63% increase compression ring life, 50% less cylinder wall wear and superior sealing characteristics, providing the engine builder and performance enthusiast with unequaled reliability.

ZGS TECHNOLOGY (ZERO GAP SECOND) - The ZGS Taper Face Ring was designed to provide superior combustion pressure control by reducing end gap leakage, as well as increase intake efficiency. Clearly the ZGS Taper Face Ring has exceeded all original expectations. The ZGS Taper Face Piston Ring stands alone as the single most significant performance advantage in piston ring technology in recent years.
Dynamometer testing over the past five years has shown that the ZGS Taper Face Ring Sets produce 9% more horsepower with an increase of 18 to 20 foot/lbs. of torque.
It is really quite simple how the Zero Gap Second Ring works. It has an overlapping step gap design to eliminate end gap blow by, in addition eliminating end gap alignment forever. The tremendous sealing ability of the ZGS Ring is very evident when you measure a cylinder's leak down. A reading of 1-1% is normal on a fresh motor.
It is now fact, not theory, that the ZGS provides a major performance advantage in all applications. Engine builders world-wide depend on the ZGS Piston Ring to provide their on-track winning performance.
Be a winner...Treat your next engine to a set of ZGS Rings for a surge of untapped power and dependability. (Made in the USA)
