Ford 9in Pinion Support Daytona Style 28 Spline

The Ford 9in Pinion Support Daytona Style 28 Spline from Moser Engineering is a critical structural component for high-performance rear axle assemblies, engineered for enthusiasts building or upgrading serious street and track vehicles. This precision-machined pinion support transfers massive loads from the driveshaft to the axle housing while maintaining perfect gear alignment under extreme acceleration, braking, and cornering forces. Whether you're constructing a restomod, drag racing platform, or high-horsepower street machine, a quality pinion support is non-negotiable for durability and consistent performance.

Constructed from lightweight aluminum with a natural finish, the Daytona-style design features a 28-spline configuration optimized for Ford 9-inch differentials—the industry-standard platform for both classic and modern high-performance builds. The aluminum construction reduces unsprung mass while maintaining structural rigidity, a critical advantage in competition and street applications where every pound counts. The Daytona-style geometry provides superior load distribution and is compatible with modern bearing preload specifications, ensuring the pinion gear stays perfectly centered regardless of torque input or suspension articulation.

This support assembly is ideal for builders upgrading from stock or worn units, particularly those running enhanced driveline power or drag racing setups where axle binding and misalignment cause premature gear and bearing failure. Installation requires proper bearing setup and preload procedures to ensure long service life—this is not a bolt-and-forget component but rather a precision part that demands careful assembly. At 3.82 lbs, it integrates seamlessly into existing Ford 9-inch housings and pairs perfectly with modern Moser Engineering gear sets, locker differentials, and custom axle shafts for complete rear-end reliability.
