YZ-4 tuned graphite upper deck

The Yokomo Z4-003S High-Flex Upper Deck (CG) is an aftermarket-style replacement for the YZ-4 4WD off-road car's upper deck position. Fabricated from graphite with a central slit, the deck raises chassis compliance compared with the factory upper deck and promotes more manageable handling.

The central slit localises bending so roll and weight transfer occur in a more progressive manner. This effect improves stability when cornering and when running over bumps or loose surfaces, making the deck a practical tuning item for varied track conditions.

Installation notes: fit in the YZ-4 upper deck location and ensure the mounting points are aligned during assembly. After installation, make incremental adjustments to suspension and weight setup to harmonise with the increased flex.

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 will added flex change corner balance on my YZ-4?

The extra compliance smooths weight transfer and can reduce abrupt snaps, giving a more gradual turn-in and stable exit when dialled in with suspension tuning.

What suspension adjustments are commonly paired with this deck?

Start with small changes to damping and spring rates, then test cornering and traction; softer settings often complement increased chassis flex but adjust by feel.

Will anti-roll or sway settings need revising?

Reassess roll resistance after fitting; reducing front or rear roll stiffness in small steps can help rebalance handling to suit the deck's behaviour.
