Tamiya 54238 M05Ra Reinforced Ball Differential Cup Set OP-1238 Off-Road Upgrade  [54238]

M-05 Drivetrain Upgrade with Tamiya 54238

The Tamiya 54238 RC M05Ra Ball Differential Cup Set is a reinforced replacement aimed at drivers who push their M-05 cars on rough or modified setups. It gives a more resilient alternative to regular aluminium cups without complicating routine service.

Reinforced Design for Tough Use

Designed to absorb higher loads and repeated impacts, these cups reduce the chance of joint failure under rally or adverse conditions. The reinforcement focuses on longevity while maintaining predictable diff characteristics.

Direct Replacement Compatibility

This Tamiya 54238 kit replaces the aluminium differential joints found in the Tamiya 54194 Ball Differential Set and fits M-05 series cars that use that assembly. The swap is intended to be simple for hobbyists familiar with the platform.
