Tamiya 51089 TB Evolution IV High-Durability Ball Bearing Pack  [51089]

Reduce Rolling Resistance on TB Evolution IV

The Tamiya 51089 Ball Bearing Set provides an effective upgrade path for TB Evolution IV platforms, including TB-EVO IV and TB-EVO IV MS. By replacing worn or stock components, these bearings help lower internal friction for a cleaner drivetrain feel.

Why add ball bearings to your setup

Bearings are a key wear item that influence gearing efficiency and drivetrain heat. The Tamiya 51089 set is matched to the TB Evolution IV geometry to improve rotation smoothness and reduce mechanical drag during both practice and race runs.

Quick maintenance and fitting guide

Ensure bearing seats and shafts are free of corrosion and debris before installation. Lightly oil the races and check for correct alignment after the first few runs. Regular maintenance will keep the parts working longer and prevent unexpected failures.
