This Yokomo YOKB2-503D differential gear is an RC-scale replacement component designed specifically for the B-Max2 platform. It installs as a direct replacement inside the differential assembly and is marketed as a hop-up spare for routine servicing or setup updates.
Compatibility is confined to the B-Max2 series per the product designation; verify your chassis layout and differential housing before ordering. Fitting the part requires standard drivetrain disassembly, careful alignment of the gears and correct seating in bearings to maintain smooth operation.
When tuning, this component alters torque transfer between driven wheels and therefore affects corner entry feel, mid-corner traction and exit behaviour; swap it in when you are testing differential settings or replacing a worn unit.
