Lightweight Bearing Upgrade for RM-01

The Tamiya 54426 adapters allow RM-01 owners to swap the factory 1150 bearings for 850 ball bearings, reducing assembly weight by roughly 3.4 grams. This small weight saving can sharpen steering response and improve rotation at the wheel hub for track-focused setups.

Fitment and Practical Use

Designed specifically for the RM-01 chassis, these plastic adapters accept 850 bearings (bearings not included) and install into the existing upright locations. After fitting, you should notice smoother wheel spin and a modest reduction in rotating mass without needing major changes to your suspension geometry.

Will these adapters work on other Tamiya models?

They are made for the RM-01 upright locations, so other models may not line up. If you plan to use them elsewhere, check measurements and trial fit first.

Do the 850 bearings come with the adapters?

No, the package contains the plastic adapters only. You will need to buy 850 ball bearings separately to complete the upgrade.

Will changing to 850 bearings affect my wheel alignment?

Swapping bearing sizes does not alter the upright geometry, but you may need to check for any lateral play and add thin shims if required to eliminate slop after installation.
