If you want to reduce drivetrain friction, the XRAY 940610 high-speed ball bearings are a practical upgrade. Sized at 6x10x3mm, these bearings are suitable for many RC car applications where smooth rotation matters.
These bearings use a denser ball count and a sturdier cage than basic types, which helps them stand up to higher loads. The rubber seals keep dust and grit out to preserve rolling quality over time.
The removable side covers make cleaning and light lubrication straightforward. A small amount of AeroShell Fluid 12 on the raceways keeps them turning smoothly and prolongs service life for both racing and street use.
