DSE Ford 9-Inch N-Series Center Section - 3.25 Ratio - 31-Spline Eaton TrueTrac - GFX 1350 Yoke - 90-20035
Build your Ford 9-inch rear end around premium components and performance-proven construction with the Detroit Speed 90-20035 N-Series Center Section. This assembled third member combines a 3.25 gear ratio with a 31-spline Eaton TrueTrac and GFX 1350 Ultra Performance yoke. The 3.25 final-drive ratio provides a numerically lower gearing option within the Detroit Speed N-Series lineup, while the TrueTrac delivers limited-slip traction through a gear-driven design. A genuine Ford SVO nodular iron H case with 3.250-inch bearings provides the foundation for the complete assembly.
Detroit Speed builds the 90-20035 with carefully selected 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 GFX 1350 Ultra Performance yoke includes a U-joint strap kit with 12-point bolts for a compatible 1350-series driveline connection. Detroit Speed individually inspects and hand deburrs the components used in its rear gear assemblies, combining premium hardware with the attention to detail expected in a performance Ford 9-inch third member.
