  • Made in the USA 🇺🇸
  • Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance.
  • A hydraulic press and professional-level tools are required for installation.
  • S&S recommends that adjustable pushrods/covers be used. Camshaft bearings and gaskets must be replaced when installing new camshafts.
