Tamiya M03M 14-piece Sealed Bearing Upgrade M03M-14 by 3Racing  [M03M-14]

M03M sealed bearing service pack

The M03M-14 kit supplies fourteen sealed 2RS bearings suitable for Tamiya M03M scale models. This selection targets rotating points where reduced friction yields a smoother drivetrain and steadier throttle response.

Use the bearings to renew wheel hubs, gearbox supports and other shafts. Their sealed construction helps retain lubricant and block grit, which is helpful when running in dusty club conditions or on well used surfaces.

Fitting advice: remove worn bearings with care to protect hub faces and diff housings, press new units evenly into place and verify free spin before completing reassembly. Replacing bearings is a simple, economical tweak that can reduce drivetrain drag.
