Tamiya 15519 HG Round Hole Ball Bearings Set (4 Pieces) for Mini 4WD - Precision Upgrade  [15519]

Tame friction with a bearing upgrade

Mini 4WD tuners aiming for cleaner roll and steadier speed will benefit from the Tamiya 15519 HG Round Hole Ball Bearings. These bearings are built to reduce internal friction and promote more efficient rotation of gears and axles.

Compatibility details

The HG Round Hole Ball Bearings fit all Mini 4WD and Mini 4WD PRO cars except those built on the Type 1 chassis. Their accurate sizing ensures a neat fit in standard mounting points, and the 2.5mm thickness helps maintain the intended clearances for competitive setups seeking reduced mechanical drag.

Expected on-track improvements

Once fitted, expect reduced drivetrain resistance which often leads to steadier top speed and improved repeatability over multiple runs. These bearings are a pragmatic choice for racers wanting incremental gains without major chassis work.
