Replacement Arm for MR-4TCSD Chassis

This Yokomo YOKSD204 servo horn set serves as an RC-scale replacement crafted for MR-4TCSD chassis applications, forming the mechanical link between the servo spline and steering linkage. The description concentrates on fit, basic installation practice, and steering behavior rather than production claims.

Fitment notes: the part is aimed at MR-4TCSD-pattern setups; verify spline count and hole spacing on your servo before attempting to install. The set is suitable as a direct swap where MR-4TCSD compatibility is listed and aligns with common 1/10 touring car steering geometries.

Fitting procedure: remove the existing horn retaining fastener, align the servo to neutral, press the replacement horn onto the spline so the wheel centering is correct, and fasten with your servo's original screw or clip. Once installed, fine-tune transmitter trims and travel endpoints to prevent binding.

Steering adjustment: swapping horn length or mounting position alters mechanical leverage and steering feel. Small positional changes will adjust initial turn-in and mid-corner balance; always recheck endpoint limits after changes.

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 the YOKSD204 built for frequent track use?

The design is intended as a serviceable replacement for MR-4TCSD setups; evaluate wear on high-load installations and replace if splines or mounting holes show deformation.

Which spline counts will this accept?

Confirm the spline count of your servo prior to purchase. The horn supports common spline patterns used in MR-4TCSD-compatible servos but must match exactly to fit securely.

Can I use this with high-torque servos?

Yes, but higher torque increases load on the horn and linkage; inspect for loosening fasteners and consider stronger mounting hardware if you run powerful servos regularly.
