Center-mount component for YZ-4S chassis

This machined aluminum centre mount is supplied as a direct replacement for YZ-4S scale RC chassis applications. It provides a firm central attachment point for centre-mount setups and helps preserve alignment between upper and lower chassis plates.

Compatibility depends on the supported chassis list and includes B-YZ4SF variants; verify your chassis code before starting. The part is purely mechanical in purpose and locates to the existing YZ-4S mounting points.

Fitting advice: remove the existing centre mount using standard disassembly of the centre section, move any necessary spacers or bushings across, and fasten with the original screws unless your chassis documentation specifies alternative hardware. Ensure screws are torqued evenly and recheck drivetrain alignment when complete.

Setup considerations: replacing the mount will modify centre stiffness and alter mass distribution in centre-motor cars, so introduce setup changes gradually and observe shock and ride-height effects on handling.

Specifications

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 an exact fit for every YZ-4S variant?

The listing covers YZ-4S and B-YZ4SF models, but manufacturing revisions can alter fit. Always confirm your chassis code and inspect mount points prior to final assembly.

What are the benefits of a machined aluminium centre mount?

Machined aluminium enhances rigidity and resists wear compared with injection-moulded parts, delivering more consistent alignment under load for centre-mount configurations.

Should I replace screws when fitting the aluminium mount?

You can usually reuse original fasteners if they are in good condition. Inspect threads and mating holes and replace any damaged hardware, tightening to the recommended torque values.

How to approach setup testing after installation?

After installation, run progressive setup tests: start with baseline shock and ride-height settings, then make incremental changes while noting handling differences to dial in desired behaviour.
