Main drive shaft for MR-4TCSD

This is an RC-scale replacement main drive shaft designed around the MR-4TCSD designation, featuring an integrated one-way mechanism to alter driven behaviour in drift setups.

The component serves as a direct drivetrain replacement where the chassis or spare-parts list cites MR-4TCSD compatibility. Its role is to transfer motor torque into the transmission while the one-way element permits differential-style free rotation under certain slip conditions, which is useful when tuning power delivery for rear-wheel drift characteristics.

Installation notes: inspect mating splines and existing bearings before fitting, ensure correct orientation of the one-way assembly, and verify clearance with the spur gear and gearbox housing. Use appropriate thread locking on any mating fasteners and retest wheel alignment after assembly. This description 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 component or when experimenting with one-way behaviour in drift package drivetrains, and follow routine gearbox inspection 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.

Is this part compatible with MR-4TCSD?

The listing references MR-4TCSD compatibility, fitment should match chassis parts labeled MR-4TCSD but verify physical dimensions with your existing shaft before installation.

What does the one-way provide in drift setups?

The one-way allows freer rotation in one direction under slip, which can change rear-wheel behaviour during drifting by reducing driveline resistance when wheels spin relative to the drivetrain.

Is the material specified for this shaft?

Material is not specified in the available listing, inspect the part on receipt or consult the seller for material confirmation if required for your setup.

Any installation tips or precautions?

Check splines and bearings for wear, align the one-way correctly, use appropriate fastener torque and threadlocker where applicable, and recheck drivetrain alignment after fitting.
