S&S CYCLE - 310-1379A - Cam Chest Kit for M8 - '17-'26 Harley-Davidson Electra Glide Police FLHTPI, Softail Low Rider ST FXLRST, Electra Glide Ultra Classic
High-lift cams put more stress on tappets and cuffs than the stock M8 setup is designed for, which is where S&S Cycle's 310-1379A kit earns its keep: billet aluminum tappet cuffs with a hard-anodized black finish resist distortion and keep S&S premium tappets stable through aggressive lift events. The kit also swaps in a precision-machined, blue-anodized billet aluminum oil pump and cam plate with independent scavenge sections and debris screens for increased oil flow on both the feed and scavenge sides. Serviceable passage plugs and an in-place adjustable pressure relief valve round it out. For '17-'26 Harley-Davidson models.
