Introduction and Specications
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 conrmed 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 conrmed 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 dicult. 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 identication 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.
