320-107 Seal Piston Rings

These piston rings by Total Seal Inc. are engineered to solve sealing challenges in Harley-Davidson engines, particularly in big bore and high-RPM scenarios. The TSS sets feature a moly-coated cast iron top ring for standard street use. The TS1 sets are intended for high-performance street and racing, utilizing a Moly Max plasma ductile iron top ring and a stainless steel oil ring expander. The inclusion of the patented Gap-less second ring ensures that blow-by is kept to a minimum, which can lead to cooler oil temperatures and more consistent power delivery. This product is sold in sets for one single piston.
