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

2.25mm Graphite Upper Deck for T4

The Arrowmax AM-T4-301195-V3 upper deck is an RC-scale replacement designed for XRAY T4 frames that require a 2.25mm graphite plate. The part is intended to alter chassis stiffness and influence handling balance without modifying suspension geometry.

Compatibility is aimed at XRAY T4 models built to the T4 2019 specification. Installation involves removing the original upper deck and moving over the factory hardware, taking care to maintain correct torque on hex screws and to check clearances around servos and electronics. No extra machining is required for standard T4 configurations.

In tuning terms, the 2.25mm graphite deck increases torsional rigidity compared to thinner plates, which commonly tightens turn-in and reduces chassis flex under cornering loads. Use it together with incremental changes to shock settings and roll centers to find the desired handling balance.

Use this upper deck when you need a predictable increase in chassis stiffness for competitive T4 driving and to test handling changes trackside.
