XRAY T4 Upper Deck 2.25mm Graphite Upgrade - Arrowmax AM-T4-301195-V3  [AM-T4-301195-V3]

Overview of the 2.25mm T4 Upper Deck

This Arrowmax AM-T4-301195-V3 upper deck serves as an RC replacement plate for XRAY T4 chassis where a 2.25mm graphite top plate is specified. The component adjusts overall chassis stiffness and shifts handling bias while leaving suspension geometry intact.

It is intended for XRAY T4 models built to the T4 2019 specification. Fit by removing the original upper deck and reusing the stock hardware, paying attention to correct hex screw torque and ensuring servo and electronics clearances are preserved. No additional cutting or drilling is required for standard T4 setups.

From a tuning standpoint, moving to a 2.25mm graphite deck increases torsional rigidity compared with thinner options, usually improving turn-in and limiting chassis movement under lateral loads. Pair this change with measured shock and roll center tweaks to find the best handling balance.

Fit this deck when you need a firmer chassis response for racing or testing and want to evaluate small handling changes on the track.
