Yokomo YZ-4 Upper Deck Plate Upgrade for YZ-4 Z4-003P  [Z4-003P]

Upper deck stiffener for Yokomo YZ-4

This aluminum upper deck plate is an optional accessory engineered for the Yokomo YZ-4 4WD off-road chassis. The plate bolts to the front and rear upper deck mounting points to create a firmer connection across the chassis top.

By raising chassis rigidity, the plate alters pitch and roll behavior and provides a simple tuning option for handling balance. Many drivers fit an upper deck plate like this to limit flex under acceleration or braking and to refine mid-corner body movement without changing suspension geometry.

Installation is straightforward: the plate uses the existing YZ-4 upper deck front and rear mounting points and fits the standard layout. Only basic hex drivers are normally required, and you may need to tweak other setup items to dial in the handling you want.
