Precision center-mount for YZ-4S platforms

This precision aluminum center mount serves as a drop-in replacement for YZ-4S scale chassis applications. It creates a firm connection point in center-mount configurations and helps maintain accurate alignment between the top and bottom sections of the chassis.

Compatibility is determined by the supported chassis codes, notably B-YZ4SF models; verify your chassis identifier before attempting installation. The part performs a structural role and connects to existing mounting bosses on the YZ-4S platform.

Installation guidance: follow standard center-section disassembly to remove the stock mount, move over any spacers or bushings as needed, and fasten with the original screws unless otherwise specified by your chassis instructions. Ensure an even torque pattern and recheck drivetrain alignment after fitting.

Tune impact: swapping to this aluminum mount will influence chassis flex and the centre of mass in center-motor layouts, so make measured setup changes to shocks and ride height while assessing handling.

Specifications

  • Item Aluminum center mount
  • Material Aluminum
  • Model Number S4-304CMA

Opt for this S4-304CMA when you require a machined aluminum center mount to keep YZ-4S chassis alignment precise and to aid centre-mount setup 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.

How long will a machined aluminum mount last compared with plastic?

Aluminum mounts resist deformation and wear much better than typical plastics under similar loads. Lifespan depends on use conditions and impacts, but aluminum generally gives longer service in center-mount roles.

Are there tolerance or fitment notes to be aware of?

This part is CNC-machined to tight tolerances, but always confirm hole alignment with your chassis before final assembly and check for any required shims or spacers.

What routine checks should I perform after installation?

Regularly inspect mounting screws for loosening, examine mating surfaces for wear, and re-check drivetrain alignment after the first few runs to confirm nothing has settled.

Is polishing or coating recommended for this aluminum mount?

A clear protective coating can help resist corrosion in damp environments, but coating is not required for fitment. Any surface finish should not alter critical dimensions or interfere with screw fitment.
