Technical summary

The Yokomo Z4-630M functions as the main drive pulley combined with an integrated slipper plate for the 4WD YZ-4 series. The aluminium pulley body houses the slipper interface to centralize the drivetrain load path on the chassis.

Intended application is limited to RC YZ-4 platforms; this part concentrates on transmission performance and does not alter suspension geometry or motor fit. The hard anodized finish improves abrasion resistance while keeping original fit to existing drivetrain parts.

When fitting, ensure the pulley meshes cleanly with the spur and pinion, fine tune slipper clearance to your preferred handling, and confirm bearings and retaining hardware are serviceable before running the car.

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 does slipper adjustment affect handling?

Loosening the slipper allows slip under acceleration, which softens traction transfer and can reduce wheel hop. Tightening improves throttle response but may increase stress on gears; tune progressively for balance.

Can this pulley be used with aftermarket spurs?

Yes, provided the spur and pinion tooth profiles and shaft spacing match the YZ-4 drivetrain geometry. Verify tooth counts and clearances to avoid interference before final installation.

Will the aluminium pulley change drivetrain efficiency?

The aluminium construction itself does not significantly alter mechanical efficiency; correct slipper setup and precise gear alignment have a larger impact on drivetrain losses and smoothness.
