Master Bearing Kit Hybrid

The ALLSTAR PERFORMANCE Master Bearing Kit Hybrid (ALL 72309) is a complete wheel bearing assembly designed for high-performance brake applications using Wilwood or AFCO hybrid rotors. This kit combines inner and outer bearings with a dust cap, hardware, and seal in a single package, eliminating the need to source components separately and ensuring compatibility across your brake system upgrade.

The hybrid rotor design represents a middle ground in thermal management and cost-effectiveness—combining iron friction surfaces with aluminum hats to reduce unsprung weight while maintaining adequate heat dissipation for sustained braking. This kit's bearing configuration is engineered to work seamlessly with hybrid rotor geometry, which requires precise tolerances and matching bearing dimensions. Included hardware and seals are matched to the bearing specifications, preventing the common mistake of mixing incompatible components that can lead to premature wear or seal failure under race or street-performance duty.

This bearing kit serves builders upgrading from OEM brakes to performance systems, whether for road racing, autocross, street performance, or off-road applications. The all-in-one format appeals to technicians and enthusiasts who value time savings and the assurance that every component is pre-matched. Whether you're installing a complete brake system or replacing worn bearings in an existing hybrid rotor setup, this kit eliminates guesswork and reduces assembly labor by consolidating four critical components into one purchase.
