DSE Ford 9-Inch HS-Series Center Section - 4.11 Ratio - 31-Spline TrueTrac - 1350 Yoke - 90-10030
Put aggressive gearing and premium driveline hardware at the center of your Ford 9-inch rear end with the Detroit Speed 90-10030 HS-Series Center Section. This performance-built third member combines a 4.11 gear ratio with a 31-spline Eaton TrueTrac differential and 1350 Ultra Performance yoke, creating a serious package for builds where acceleration, traction and driveline strength are priorities. The HS-Series uses a Ford SVO nodular iron H case with a 3.250-inch bearing that Detroit Speed states is approximately 4.5 pounds lighter than its standard Ford 9-inch N-Series case.
Detroit Speed builds the 90-10030 with premium components throughout, including a Ford Daytona pinion support, ARP pinion support bolts, safety-wired ARP ring gear bolts, premium ring and pinion, solid pinion preload spacer and TIMKEN bearings. The Eaton TrueTrac provides gear-driven limited-slip operation without conventional friction clutch packs, while the 1350 Ultra Performance yoke includes a U-joint strap kit with 12-point bolts. Detroit Speed also individually inspects and hand deburrs the components used in its rear gear builds, making this a thoroughly engineered center section for high-performance Ford 9-inch applications.
