Carrier Bearing Set

The RATECH Carrier Bearing Set (Part 9001) is a precision roller bearing assembly engineered to support the carrier shaft in differential housings across a wide range of domestic platforms. This pair delivers the critical radial and thrust load capacity required to maintain proper carrier geometry and minimize operational play in AMC Model 20, Dana, Ford, and GM/Mopar differentials during both street and high-performance driving conditions.

Constructed from hardened steel with matched races, these carrier bearings are designed to handle the compressive and rotational forces generated during acceleration, deceleration, and cornering. Proper bearing fit and preload are essential to preventing carrier walk—a condition that degrades mesh pattern, increases backlash, and accelerates gear wear. The standardized geometry of this RATECH set ensures compatibility with factory bearing pockets while maintaining the OEM preload specifications required for optimal differential function and longevity.

This bearing pair is essential for anyone rebuilding or servicing a differential on classic muscle cars, trucks, or performance-modified vehicles where the original bearings show wear, spalling, or preload loss. Restoration builders, transmission shops, and serious hobbyists rely on OEM-spec carrier bearings to restore proper differential function and prevent recurring gear noise and play issues. The weight of 1.67 lbs reflects the robust construction typical of bearing assemblies engineered for heavy-duty automotive service.
