• Material must be removed from inner surface of the stock gear cover to install
• A hydraulic press and other professional level tools are required to install the kit
• High lift valve springs and adjustable pushrods required
• Camshaft bearings and gaskets must be replaced when installing new camshafts
• Kit includes camshafts, inner gear, outer drive gears, inner, outer bearings, gasket and instructions

  Notes: Installer must check coil bind, valve to valve clearance and valve to piston clearance.
  Due to inherent characteristics of gear drives, you may experience more valve train noise.
  
  Note: Kit requires high performance valve springs when installed in '99-'04 models.
  Cams for '00-'06 Twin Cam are for use with stock splined drive gears; for installation on '99 Twin Cam motors you must purchase splined outer drive sprocket; S&S recommends Andrews 4340 steel driver sprocket.
