The Yokomo Z4-630M is the standard main drive pulley/plate designed for the 4WD off-road YZ-4 series. The part combines an aluminum pulley body with an integrated slipper plate to centralize the drivetrain interface for the chassis.
Intended use is limited to RC-scale YZ-4 models, and the component focuses on transmission roles rather than suspension or motor changes. The hard anodized finish provides surface wear resistance without altering fitment to existing drivetrain parts.
Installation notes: confirm the pulley aligns with the spur and pinion, ensure the slipper adjustment is set to match your driving conditions, and inspect bearings and retaining hardware already on the car for correct fit before running.
