Detroit Speed's Ford 9" HS-Series Rear Gear is built using the Ford Racing Investment Cast 3.250 in. bearing case. This case is about 4.5lbs lighter than the standard Ford 9" N-Series case. All Detroit Speed rear gear builds use championship winning build procedures and attention to detail. All parts are individually inspected and hand deburred for quality assurance. Only the highest quality parts are used to produce a product that meets Detroit Speed standards.
