S&S CYCLE - 310-1005B - Cam Chest Kit for M8 - '17-'26 Harley-Davidson Electra Glide Police FLHTPI, Softail Low Rider ST FXLRST, Electra Glide Police FLHTP
Ditching the stock cam chain tensioner for gear-driven timing is the headline change in S&S Cycle's 310-1005B cam chest kit for '17-'26 Harley-Davidson M8 models, along with the timing accuracy gains that go with it. The blue-anodized billet aluminum oil pump and cam plate split scavenging into independent sections for the flywheel cavity and cam chest, each guarded by a debris screen, for more oil flow on both sides. Every part in the kit is matched, and the relief valve adjusts without pulling the unit.
