Overview: MR-4TCSD Main Drive Shaft

This RC-scale replacement main drive shaft is built around the MR-4TCSD reference and includes an integrated one-way mechanism to alter driven response in drift setups.

The component is intended as a direct drivetrain replacement where parts lists specify MR-4TCSD compatibility. It transfers motor torque into the transmission while the one-way unit permits freer rotation in one direction under slip, which helps modify rear-wheel behaviour when tuning for drifting.

Installation notes: inspect mating splines and bearings before fitting, confirm the one-way is orientated correctly, and check clearance with the spur gear and gearbox housing. Apply threadlocker to fasteners as needed and recheck wheel alignment after assembly. This guidance assumes familiarity with common hobby tools and basic gearbox disassembly.

Specifications

  • Item: Main drive shaft with one-way.
  • Material: Not specified.
  • Model Number: YOKSD644TS.
  • Compatibility: MR-4TCSD.

Use this shaft when replacing a worn MR-4TCSD main drive part or when testing one-way behaviour in drift package drivetrains, and perform routine gearbox checks after installation.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this fit my MR-4TCSD chassis without modification?

The listing specifies MR-4TCSD compatibility, but you should compare the shaft splines and overall length with your current part to confirm fitment before installation.

How does the one-way affect drifting performance?

The integrated one-way reduces driveline resistance when wheels slip in the free direction, which can make rear-end breakaway and sustained slides easier to control in drift setups.

Is the shaft material listed?

Material is not specified in the listing. Inspect the part on receipt or contact the seller for material details if this is critical for your build.

Any installation tips I should know?

Check splines and bearings for wear, ensure correct one-way orientation, torque fasteners to spec, use threadlocker where appropriate, and verify drivetrain alignment after fitting.
