FAG 501083 Transfer Case Output Shaft Race

Transfer Case Output Shaft Race for Heavy-Duty Drivetrains

FAG 501083 is a tapered roller bearing race built for demanding drivetrain service in transfer cases, transmissions, differentials, and wheel-end applications. Its compact design and load-carrying capacity make it a practical replacement for a wide range of Ford, Chevrolet, GMC, Ram, Mercedes-Benz, and Corvette applications.

Key Features

• FAG transfer case output shaft race, part number 501083
• Tapered roller bearing design for high load capacity
• Compact bearing profile for drivetrain packaging requirements
• Measures 0.625 in. length (15.88 mm)
• Bearing outside diameter: 0.75 in. (96.84 mm)
• Cross-references National 382A and Pioneer Automotive Industries 501083

Detailed Description

This FAG 501083 bearing race is engineered for drivetrain assemblies that see sustained load and rotational stress. As a tapered roller bearing component, it supports axial and radial forces while maintaining the compact dimensions needed in transfer case and axle applications. It is a direct-fit service part for many rear inner, rear, and front inner positions across light-duty and heavy-duty trucks, vans, and performance cars. Common search terms for this part include FAG 501083 transfer case output shaft race, rear inner bearing race for Ford F-350 Super Duty, and Chevrolet Silverado 2500 HD rear bearing race.

Compatible vehicle coverage includes Ford E-350 Super Duty, Ford Transit-150/250/350, Chevrolet Silverado 2500 HD, GMC Sierra 2500 HD, and Chevrolet Corvette applications listed in the fitment data. The FAG 501083 part number is also used across older GM truck and van platforms, making it a useful reference when matching axle and drivetrain service parts.

What It Helps Address

• Excessive bearing wear in transfer case or axle assemblies
• Noise from a worn rear inner or front inner bearing race
• Loose or rough drivetrain rotation under load
• Service replacement needs on high-mileage truck and van drivetrains
• Fitment matching for applications using National 382A / Pioneer Automotive Industries 501083

Installation Notes and Tips

• Verify the bearing dimensions before installation: 0.625 in. length and 0.75 in. outside diameter.
• Confirm the exact position listed in the fitment data, such as rear inner, rear, or front inner.
• Inspect the mating shaft, hub, or race surface for scoring or heat damage before assembly.
• Use proper bearing service procedures and press tools to avoid damaging the race during installation.
• Match axle and ring gear notes carefully on GM, Ford, and Ram applications, especially on heavy-duty configurations.

Quality Assurance

FAG is a Schaeffler brand with extensive tapered roller bearing production experience, manufacturing over 100 million tapered roller bearings annually. That manufacturing scale supports consistent bearing construction for service applications such as the FAG 501083 transfer case output shaft race.
