This Yokomo YOKB2-503D differential gear is an RC-scale replacement component intended for the B-Max2 platform. It functions as a direct swap for the differential assembly and is offered as a hop-up spare for servicing or setup changes.
Compatibility is limited to the B-Max2 series as indicated by the product designation; confirm your chassis and differential housing before ordering. Installation involves basic drivetrain disassembly and reassembly, taking care to maintain correct gear alignment and minimal runout when seating the unit in the existing bearings.
From a setup perspective the unit changes how drive torque is split between driven wheels, influencing corner entry, mid-corner traction and drive-out behavior; fit it when validating differential settings or when the original unit shows wear.
