320-111 Seal Piston Rings

Total Seal Inc. offers these piston ring sets to enhance the efficiency of Harley-Davidson power plants. The TSS line uses a moly-coated cast iron top ring, while the TS1 line is built for extreme environments using a Moly Max plasma ductile iron top ring. Central to both is the patented Gap-less second ring, a two-piece design that eliminates the traditional end gap. This prevents combustion pressure from escaping into the crankcase, significantly reducing blow-by and improving overall engine longevity. The TS1 oil ring features tool steel, chrome-faced rails for maximum durability. This product is sold in sets for one single piston.
