Aeroflow Hitachi style high torque starter motors are serviceable and manufactured from aluminum with a multi-angle mounting block that allows different mounting positions to clear multiple header and oil pan configurations. The 1.4kw / 1.9hp starter is recommended for engines up to 400cu and 14:1 compression ratio and utilizes a 4.44:1 gear reduction. Aeroflow starter motors have high heat resistance and are powder coated black for extra corrosion protection.
