S&S Cycle Forged Roller Rocker Arms - 900-1084

Big lift cams can open up the high rpm potential of the M8 powerplant, but they can also cause their own issues due to the extra stresses and stock valvetrain geometry. Excessive valve thrust and valvetrain wear drove S&S engineers to design stronger, more durable components that will help you get the most out of your M8. S&S Forged Roller Rocker arms for M8 models are stronger, more durable and easier on the rest of your valvetrain, and are essential for increasing the longevity of your valvetrain components on cams with greater than .550" lift.
