NOTES:
 2005-up stock valve springs will handle camshafts with lift up to 0.585". If a camshaft with higher lift is installed, high performance valve springs
capable of handling a greater lift must be used.
 A cam with over 0.585” of lift will cause interference between the valve spring top collar and the valve seal with stock valve springs.
 Piston to valve clearance will need to be conrmed when using a cam with over 0.585" of lift. Clearance should be at least 0.060" intake and .080"
exhaust.
 Valve to valve clearance will need to be conrmed when using a cam over 0.585" lift. Clearance should be a minimum of 0.060".
 Installation of S&S chain drive cams requires special tools. See Picture 1 for the required tools. Attempting the cam change operation without these
tools will be dicult. Damage can result which will not be covered under warranty.
 Possible failure may result if thread locking compound is not applied to the cam drive sprocket ange bolts. Always prepare threads according to the
instructions on the container.
 All reference to Harley-Davidson part numbers is for identication purposes only. We in no way are implying that any of S&S Cycle’s products are
original equipment parts or that they are equivalent to the corresponding Harley-Davidson part numbers.
