TAMIYA DB-01 Ball Bearing Upgrade Steel Set BS-DB01/V1 by 3Racing  [BS-DB01/V1]

DB-01 Bearing Upgrade

This ball bearing set is a direct replacement option for the TAMIYA DB-01 chassis, sold as BS-DB01/V1. The kit uses steel precision bearings to cut rotational resistance in the drivetrain and steering linkages.

Installed in place of factory bushings or worn bearings, these parts restore smoother wheel and gear rotation and help keep throttle and steering inputs predictable during running. The set is aimed at routine maintenance and basic tuning rather than external chassis modification.

Installation notes: follow the DB-01 service instructions to remove old bushings or bearings, check axle journals and gear interfaces for wear, press the new bearings into position and refit components per the manual. Periodic inspection and a light bearing lubricant will keep steel bearings performing reliably.

Tuning benefit: precision bearings reduce parasitic drag through the drivetrain, sharpen repeatable input feel and make it easier to isolate vibration or binding issues that affect lap consistency. Use BS-DB01/V1 as a simple hop-up when prepping a DB-01 for track or club use.
