S&S Cycle Oil Control Valve for Oil Cooled 2017-Up Harley-Davidson M8
The factory oil control valve on oil-cooled M8 engines regulates oil flow to the cooler and heads – but the stock check ball retainer is formed steel that can fatigue and fracture, sending metal chips through the oil circuit and into the tank. The S&S Cycle oil control valve replaces that assembly with a more durable design that eliminates this failure point before it becomes a problem.
