Yokomo S4-304CMA Aluminum Center Mount for YZ-4S  [S4-304CMA]

Center mount for YZ-4S

This aluminum center mount is a direct replacement part intended for YZ-4S scale RC chassis applications. It provides a rigid anchor point for center-mount configurations and is suitable where builders need a durable machined part to maintain alignment between upper and lower chassis sections.

Compatibility is defined by the supported chassis listing, specifically B-YZ4SF models; verify chassis code before installation. The part's role is mechanical and setup-oriented, not electrical or electronic, and it interfaces with existing mounting points on the YZ-4S platform.

Installation notes: remove the stock center mount following standard disassembly of the center section, transfer any required spacers or bushings, and secure using the original fasteners unless replacement hardware is specified by your chassis manual. Check for even torque on mounting screws and confirm drivetrain alignment after assembly.

Tuning role: this mount affects chassis stiffness and center mass distribution in a center-motor layout, so changes to the mount material or mounting height can be used as part of incremental setup adjustments alongside ride height and shock settings.

Choose this mount when you need a machined aluminum replacement for the YZ-4S center section to preserve chassis alignment and support center-mount setup adjustments.
