The motor and gear assembly features five sealed bearings that improve wear and reliability. Heat resistant, integrated solenoid operates even at extreme temperature. Smaller size provides better oil pan and exhaust clearance. Unique mounting system allows the starter to be rotated in 20 degree increments for improved header clearance. Assembled in the USA.
