Extend Ball Differential Life with Tamiya 42171

The Tamiya 42171 RC 620 HC Thrust Bearings are made to be disassembled so you can tweak the number of balls in the assembly. This lets you tune the differential for longer service life and cleaner rotation under load.

Included Parts and Adjustment

This set includes two thrust washers plus eight 1/16-inch balls. By varying the ball count you can tailor wear characteristics and smoothness to match your driving surface and maintenance schedule.

Start with the full complement, then remove one or two balls to test feel. Track wear and adjust toward more balls if you see faster wear in heavy use.
Many older models that use ball differentials will accept these thrust bearings, but double-check fit and clearance before final installation.
Keep the parts clean, use light oil or grease recommended for diffs, and inspect balls for nicks. Regular checks after running sessions prevent premature wear.
Basic hobby tools like fine tweezers, needle-nose pliers and a small screwdriver are enough. A parts tray helps keep the balls from rolling away.
