DSE Ford 9-Inch Aluminum Center Section - 3.50 Ratio - 31-Spline Eaton Truetrac - 90-00015
Build your Ford 9-inch rear end around a performance-focused combination with the Detroit Speed 90-00015 Ford 9-Inch Aluminum Center Section. This assembly combines a 3.50 gear ratio with a 31-spline configuration and Eaton Truetrac differential, giving performance street and Pro Touring builds a versatile gearing and traction package. The 3.50 ratio provides a strong balance between acceleration and comfortable cruising, making this center section a solid choice for cars expected to perform on the street as well as during spirited driving.
At the heart of the 90-00015 is an Eaton Truetrac differential, which uses a gear-driven limited-slip design rather than traditional clutch packs. That means there are no friction clutches to wear out or require periodic replacement. Combined with the aluminum construction, 31-spline configuration and 3.50 gearing, this Detroit Speed center section provides a well-matched foundation for a performance-oriented Ford 9-inch rear axle assembly.
