S&S HIGH PERFORMANCE TAPPETS
S&S Cycle announces the introduction of a new line of premium high performance tappets for 1999-'13 Harley-Davidson® big twin and 2000-'13 Sportster® models. These High Performance Tappets are intended for demanding street riders and racers, but are great in any Harley-Davidson motor Machined to a higher standard, they provide optimized leak down rates for quick pump up, consistently quiet operation, and superior stability at high rpm. A low mass, bearing grade, silicon nitride check ball and a lighter ball spring, allows these tappets to operate efficiently on lower oil pressure. They pump up quickly and stay quiet from start-up to the end of the ride, even with high oil temperatures. Thanks to the close tolerances and low leak-down rate they also handle high lift cams and heavier valve springs with ease, extending the usable rpm range. Precise top end oil metering delivers just the right amount of oil to the rocker arms, resisting leaks and oil carry over from too much oil, as well as premature rocker and valve wear from insufficient top-end oil supply. S&S Premium High Performance Tappets are available with or without the S&S HL2T limited travel kit installed. With the close tolerance and optimum leak down rate of these lifters, the main benefit of the limited travel kit is improved starting for motorcycles not equipped with S&S Easy Start Cams. Sold in sets of four only.
