S&S Cycle Tappet Cuffs for 2017-Up Harley-Davidson M8 Models

S&S Cycle Tappet Cuffs for 2017-Up Harley-Davidson M8 Models

Factory M8 tappet guides leave tappets vulnerable to rotational twisting under high stress – when a tappet rotates in its bore, valve actuation suffers and wear accelerates rapidly. S&S Cycle Tappet Cuffs capture each tappet without restricting vertical motion, keeping them precisely aligned under sustained hard acceleration and high-rpm operation.
