Top plate description for YZ-4 chassis

This item is the standard graphite upper deck intended for the YZ-4 4WD off-road scale car and is listed under Yokomo part number Z4-003. Used as a top-plate swap, it functions as a tuning component to modify top-side stiffness and chassis behaviour without changing suspension or drivetrain components.

Made from graphite, the deck is aimed at RC tuning: competitors use it to influence chassis flex characteristics, initial turn-in and balance through mid-corner. Since the part is dedicated to the YZ-4 platform, confirm your chassis variant matches the supported models before installation.

Installation notes: this upper deck attaches to the chassis via the vehicle's existing upper-deck mounting points. When fitting, ensure correct alignment with B-YZ4 mounting bosses, confirm supplied hardware with the seller, and perform staged setup checks to evaluate handling effects.

Compatibility

  • B-YZ4
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 the Z4-003 compatible with aftermarket YZ-4 variants?

The deck is designed for YZ-4 platforms and specifically references B-YZ4 support. For modified or aftermarket chassis, compare mounting points to confirm fitment before ordering.

Will I need extra spacers to fit this plate?

Spacing requirements depend on your current hardware and any chassis modifications. The product listing does not guarantee supplied spacers; inspect the seller details and plan for common reuse of existing fasteners.

How should I evaluate handling after fitting?

Fit the deck and test the car progressively: check turn-in, mid-corner balance and overall responsiveness. Note changes and adjust shock, anti-roll and toe settings to regain the desired balance.
