Refine driveline response with Tamiya 53379 3mm balls

The Tamiya 53379 3mm Lightweight Differential Ball Set for RC Cars OP-379 provides an easy upgrade to trim rotating mass inside ball-type differentials. By using lighter balls you can achieve smoother engagement and a more consistent transfer of torque, which helps drivers who demand precise throttle modulation.

Intended applications

These balls are suited to a range of Tamiya models that use traditional ball diffs. They work well when combined with proper diff oil selection and routine maintenance to maintain predictable lock and slip characteristics across varied driving conditions.

Simple fitment advice

Fitting involves disassembling the differential, replacing the existing balls with the 3mm lightweight set, checking gear mesh and bearings, then reassembling. Clean the internal components and apply fresh grease or oil as recommended to prolong service life.

How do I confirm my diff uses 3mm balls?

Refer to your model manual or inspect the diff internals; measure an existing ball if unsure. Only fit these if the diff uses 3mm ball components.

Will these reduce overall drivetrain losses?

They lower rotational inertia inside the diff which can slightly reduce drivetrain losses, giving a marginal improvement in responsiveness rather than a large power gain.

Any tips to avoid losing the small balls during service?

Work over a tray, use magnetic or soft-jawed tweezers if possible, and keep the workspace well lit. Handle one ball at a time to reduce the chance of losing them.
