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

Precision aluminum deck plate for YZ-4

This aluminum upper deck plate is a bolt-on upgrade for the Yokomo YZ-4 4WD off-road chassis. The component secures to the upper deck front and rear mount points to form a firmer connection across the chassis top.

Increasing chassis rigidity alters the pitch and roll response and acts as a simple tuning tool for handling. Pilots commonly fit an upper deck plate to limit flex under acceleration or braking and to fine tune body motion without changing suspension geometry.

Installation is direct and uses the existing YZ-4 upper deck mounting pattern. No specialist tools are normally required beyond standard hex drivers, and you might need to tweak other setup parameters to reach your target handling.
