Sealed Power Piston Ring Set, Speed Pro Series, 4.030" Bore, 1/16" x 1/16" x 3/16" Thick, Standard Tension, Plasma Moly, 8-Cylinder

Sealed Power plasma-moly piston rings are designed to stand up to the rigors of racing and high performance street use, while providing a long service life. Just look at some of these features: Plasma-moly coated, barrel-shaped, ductile iron top rings that seal against blowby when the piston rocks in its bore; tapered secondary rings that seal against the oil control ring's upper surface for excellent oil control; and 3-piece oil rings with stainless steel expanders that provide proper tension without robbing horsepower.
