DSE Ford 9-Inch Aluminum Center Section - 35-Spline Truetrac - 90-01000
Build your Ford 9-inch rear end around a heavy-duty 35-spline configuration with the Detroit Speed 90-01000 Aluminum Center Section. Detroit Speed pairs this aluminum Ford 9-inch assembly with a 35-spline Truetrac differential, making it a performance-oriented option for builders who need a higher spline-count configuration than the 31-spline versions in the Detroit Speed lineup. For high-performance street, restomod and Pro Touring projects built around compatible 35-spline axles, the 90-01000 provides the core center-section configuration needed to complete the rear axle package.
The 90-01000 uses a Truetrac limited-slip differential, a gear-driven design that operates without conventional friction clutch packs. This provides automatic limited-slip operation while eliminating the traditional clutch packs found in many other limited-slip differential designs. Detroit Speed lists the gear ratio for this specific part as X.XX rather than identifying one fixed ratio, so the required gear ratio should be confirmed when ordering. That distinction is important because 90-01000 should not be confused with Detroit Speed's fixed-ratio 31-spline Ford 9-inch center sections.

Fitment Notes
Detroit Speed identifies part number 90-01000 as a Ford 9-inch aluminum assembly with a 35-spline Truetrac differential. Unlike the fixed-ratio 31-spline center sections, the manufacturer identifies the gear ratio for 90-01000 only as X.XX. Confirm the required gear ratio along with axle spline count and all other rear axle compatibility requirements for your specific build before ordering.
FAQs
What gear ratio does the DSE 90-01000 use?
Detroit Speed does not specify one fixed gear ratio for part number 90-01000. The current manufacturer listing identifies it as X.XX, so the required gear ratio should be confirmed when ordering rather than assuming a specific ratio.
What spline count does the DSE 90-01000 use?
Detroit Speed specifies the 90-01000 as a 35-spline Ford 9-inch assembly. It therefore needs to be matched with compatible 35-spline axles and the appropriate rear axle components for the build.
What differential is used in the DSE 90-01000?
The 90-01000 uses a Truetrac limited-slip differential. Its gear-driven design provides automatic torque biasing without relying on conventional friction clutch packs.
