Graphite upper deck tuned for YZ-4 handling

The Yokomo Z4-003S High-Flex Upper Deck (CG) serves as a replacement upper deck crafted for the YZ-4 4WD off-road car. Constructed from graphite and incorporating a central slit, the deck increases chassis flex relative to the stock component to yield smoother, easier-to-manage reactions.

By concentrating bend around the slit, the deck encourages more progressive weight transfer and controlled roll. That behavior aids stability when cornering or navigating uneven ground, making this deck a sensible tuning option for rough or loose surfaces.

Installation notes: intended specifically for the YZ-4 upper deck position; take care to align mounting points during installation. After fitting, evaluate handling stepwise and modify suspension or balance settings to complement the greater flexibility.

Compatibility

  • Yokomo YZ-4 4WD off-road 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 durable is the graphite material under rough track use?

Graphite offers a good stiffness-to-weight ratio; the design focuses flex into the slit while keeping overall strength suitable for typical off-road conditions.

Does the central slit make the deck prone to cracking?

The slit increases local flex rather than creating a stress riser when fitted correctly; check mount alignment and avoid overtightening screws to reduce risk.

What care helps extend the life of this deck?

Regularly inspect mounting hardware, clear debris from the slit area, and replace if you notice any hairline damage from impacts.
