Tamiya F104 Replacement Ball Bearing Set BS-F104/V1 by 3Racing  [BS-F104/V1]

About the F104 bearing pack

This ball bearing pack is intended for the Tamiya F104 chassis and is referenced under model BS-F104/V1. It provides a direct replacement route for worn or low-spec bearings used in 1/10 scale formula and touring cars built on the F104 layout.

The bearings are designed to cut rolling resistance at key rotating points such as hubs, motor outputs and gearbox bearings, which helps with throttle precision and consistent drivetrain behaviour during extended running. Fitment notes apply to F104-style RC assemblies only, not to non-RC or full-size machinery.

Installation is usually a standard bearing change: remove the old bearings, clean the seating faces, and press the new bearings in squarely to prevent misalignment. After install check for smooth rotation and any lateral play, and perform routine cleaning and light lubrication to retain performance.
