The Yokomo YOKB2-503D differential gear is produced as an RC replacement part for the B-Max2 platform. It is suitable as a direct replacement inside the differential assembly and works as an aftermarket spare for maintenance or setup trials.
Fitment is specific to the B-Max2 family as stated by the product code; verify your chassis and housing compatibility before purchase. Installing the unit requires careful drivetrain strip-down and reassembly, attention to gear mesh and bearing seating will help avoid premature wear.
In terms of setup this differential affects torque distribution across the driven wheels and will influence turn-in, mid-corner grip and acceleration out of corners; replace it when experimenting with settings or when the factory part shows signs of wear.
