Improve Differential Durability with Tamiya Tungsten Balls

Tamiya's tungsten thrust bearing balls (part number 42193) are made to strengthen the thrust surfaces in TRF differentials. Machined from tungsten, these balls give better wear resistance than standard steel, helping the thrust bearing last longer and keeping drivetrain feel consistent during hard use.

Fitment and Applications

These tungsten balls suit a range of Tamiya TRF chassis, including TRF416, TRF416WE, TRF416X, TRF417, TRF201, TRF511, and TRF502X. They are a practical choice whether you are prepping a car for club racing or maintaining a daily runner.

Advantages of Tungsten Material

Tungsten offers higher hardness and improved resistance to surface wear, which reduces how often the thrust bearings need replacing. That reliability helps preserve setup consistency and reduces routine maintenance time.

Can I use these balls in non-TRF Tamiya diffs?

These balls are intended for the TRF series models listed above. If you plan to fit them to other Tamiya diffs, check the diff inner dimensions and ball size to confirm compatibility.

Do tungsten balls need a special lubricant?

Tungsten itself does not require unique grease, but assemble the thrust bearing with the same diff oils and greases you normally use. Good lubrication and correct assembly are key to long service life.
