Yokomo YOKB2-501GS Drive Cup for B-MAX2 MR/RS Gear Differential  [YOKB2-501GS]

Drive cup suited to B-MAX2 MR and RS

This item is a gear differential drive cup intended for Yokomo B-MAX2 MR and B-MAX2 RS 1/10 electric touring cars. It connects the differential output to the driveline and is made for routine replacement and service.

Fitment covers only the specified B-MAX2 MR/RS variants; verify compatibility against your chassis parts list. Prior to fitting the new cup, inspect the differential splines and output shaft for wear, burrs, or deformation and renew any damaged components to prevent early failure of the new cup.

Installation guidance: follow the chassis instructions to remove the differential, slide the drive cup onto the output, and confirm correct engagement with the drive axle or dogbone. Reuse serviceable hardware and use thread-lock where the chassis manual indicates.

Role in setup: primarily a serviceable replacement part. While it is not a tuning upgrade, ensuring minimal clearance and correct seating will help sustain consistent drivetrain behavior and clean power delivery on-track.
