Pinion Bearing Daytona (35 SPLINE)

The Pinion Bearing Daytona (35 SPLINE) is a precision roller bearing engineered for high-performance Ford 9-inch differential applications, particularly in drag racing and street performance builds. As a mechanic working on serious drivetrain upgrades, you'll recognize this as an essential component for any pinion shaft assembly carrying significant torque loads. The Daytona designation signals heavy-duty durability—this bearing handles the radial and axial forces generated during hard launches, cornering, and sustained acceleration that stock bearings simply cannot endure.

Built with steel construction, the Pinion Bearing Daytona features a 3.000-inch outer diameter and 1.313-inch inner diameter, dimensions that match OEM and performance gear set specifications for seamless integration. The 35-spline configuration aligns with modern high-strength pinion designs, allowing full torque transmission without slip or wear. At just 1.43 pounds, this bearing combines minimal rotating mass with maximum load capacity—critical for reducing parasitic drag while maintaining the structural integrity needed for 500+ horsepower applications and nitrous oxide or supercharger combinations.

Installers and engine builders upgrading Ford 9-inch rear ends benefit from this bearing's compatibility with both OEM carrier assemblies and aftermarket Pro Gear differential packages. Whether you're refreshing a worn differential or building a dedicated strip car, proper pinion bearing selection prevents premature failure and catastrophic gear damage. Installation requires careful alignment with the pinion depth gauge and crush sleeve adjustment—precision work that separates reliable builds from costly failures. This bearing is sold individually, so confirm your complete differential kit requirements before ordering.
