Speed Pro Plasma Moly Racing Rings
Designed to make more horsepower and last longer. Top rings are made from virtually unbreakable, high strength ductile iron with a plasma moly facing for instant seating and long life. Second rings are cylinder friendly cast iron with an oil controlling taper face profile and an intentional open gap design that reduces inter-ring pressure buildup. Exclusive electro-polished stainless steel SS60 oil rings prevent the high rpm deflection. Excellent oil control at the highest rpm.
