Cast Iron 9 Inch Pinion Support H8896

“Daytona” pinion bearing supports use larger bearings and strengthen a known weak point onFits Ford 9-inch axle assemblies. Designed byFits Ford in the 1960’s to take the punishment of NASCAR racing, the larger bearings of the Daytona pinion support significantly reduce pinion gear deflection to improve durability. Gear deflection occurs when the pinion shaft moves out of alignment under heavy loads, causing the tooth contact pattern to change. Reduced tooth contact (under heavy load) with the ring gear typically leads to catastrophic axle failure.  Daytona pinion bearings are set up differently than traditionalFits Ford 9-Inch pinions you’ll find under most cars, trucks, and vans (but they’ll easily adapt to all of them). By using bearing spacers with shims rather than a traditional crush sleeve, the solid spacer and shim pack won’t deform under load. This maintains critical depth settings which helps preserve that important tooth contact pattern.  Plus, this set-up makes gear ratio swaps, yoke upgrades and third-member rebuilds much easier. Just re-insert the shims and torque the pinion nut to set pinion depth! Fits all 1.218” 28-splineFits Ford 9-inch pinion gears. The benefits of Daytona bearing retainers don’t end there. Our Daytona pinion support features a beefed-up nodular iron housing. Nodular iron, also known as ductile iron, has greater tensile strength and is less prone to fracturing than ordinary “gray” cast iron. Plus, larger oiling channels ensure more gear oil flows across the bearing, extending bearing life. Milled gasket surfaces ensure a leak-free seal. Whether you’re upgrading an OEMFits Ford 9-inch or building a stout rear end from the ground up, don’t take shortcuts! Improve reliability and longevity with a nodular iron Daytona pinion bearing support. Increases durability and strengthens a known weak point inFits Ford 9-inch axle assemblies. Larger bearing adds strength, reduces gear deflection in high horsepower/torque applications
