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

Drive cup for B-MAX2 MR/RS

This is a replacement gear differential drive cup intended for use in Yokomo B-MAX2 MR and B-MAX2 RS 1/10 scale electric touring models. The part is designed to interface with the gear-type differential assembly and serves as the connection between the differential output and the driveline.

Compatibility is limited to the listed B-MAX2 MR/RS variants only, follow your chassis parts list to confirm fit. When swapping this drive cup, inspect the mating splines on the differential and the output shaft for wear or deformation before installation. Replace worn items to avoid accelerated wear on the new cup.

Installation notes: remove the differential assembly according to your chassis procedure, slide the drive cup onto the differential output, and verify engagement with the drive axle or dogbone. Check for free rotation and absence of binding before final assembly. Use existing hardware and thread-lock where specified by chassis guidelines.

Tuning role: the drive cup is a maintenance and repair item rather than a tuning part, but correct fit and low play in the interface help maintain predictable drivetrain response and consistent power transfer during acceleration and cornering on-track.
