The Hitach H190 differential has a 190mm (7.49 inch) ring gear and can handle about 285 lb. ft. of torque, making it suitable for larger V6 or drag racing supercharged 1200s. H190 is the strongest live axle Hitachi fitted to Datsun cars (C200 from pickups is larger), and is available with lightweight aluminium carriers and a variety of stock ratios.
