XRAY T4 2.25mm Graphite Upper Deck for Chassis Tuning - Arrowmax AM-T4-301195-V3  [AM-T4-301195-V3]

T4 2.25mm Graphite Upper Deck Overview

The Arrowmax AM-T4-301195-V3 upper deck is an RC replacement plate made for XRAY T4 layouts that call for 2.25mm graphite. The part is intended to change chassis stiffness and affect handling balance while keeping suspension geometry unchanged.

Fitment is targeted at XRAY T4 cars built to the T4 2019 specification. Remove the factory upper deck and transfer original hardware during installation, keeping hex fasteners at correct torque and checking clearances around the servo and electronics. Standard T4 arrangements require no extra machining.

From a setup viewpoint, a 2.25mm graphite deck raises torsional rigidity over thinner plates, which generally sharpens turn-in and reduces chassis flex under load. Combine this change with small shock and roll center tweaks to reach a stable on-track balance.

Choose this upper deck when you want a controlled increase in chassis stiffness for competitive T4 setups and to evaluate incremental handling changes at the track.
