S&S CYCLE - 310-1118B - Cam Chest Kit for M8 - '17-'26 Harley-Davidson Electra Glide Police FLHTPI, Softail Low Rider ST FXLRST, Electra Glide Police FLHTP
S&S Cycle's 310-1118B takes on two common failure points in aggressive M8 cam setups, tappet cuff distortion and oil starvation at high rpm, with billet aluminum tappet cuffs that carry a hard-anodized black coating for strength beyond stock, holding S&S premium tappets stable under high lift, and a precision-machined, blue-anodized oil pump and cam plate with independent scavenge sections and debris screens for more oil flow on the feed and scavenge sides alike. Passage plugs stay serviceable and the pressure relief valve adjusts in place. Fits '17-'26 Harley-Davidson models.
