XRAY T4 Upper Deck 2.25MM Graphite by Arrowmax AM-T4-301195-V3  [AM-T4-301195-V3]

Upper deck for XRAY T4 (2.25mm graphite)

This Arrowmax AM-T4-301195-V3 upper deck is an RC-scale replacement part designed for XRAY T4 chassis where 2.25mm graphite plates are specified. The component is intended to alter chassis stiffness and influence handling balance without changing suspension geometry.

Fitment targets XRAY T4 models built to the T4 2019 specification. Install by removing the factory upper deck and transferring required hardware, taking care to maintain torque on hex screws and to verify clearances around the servo and electronic components. No additional machining is required for standard T4 layouts.

From a tuning perspective, a 2.25mm graphite upper deck increases torsional rigidity relative to thinner plates, which typically sharpens turn-in and reduces chassis flex under load. Use it alongside incremental adjustments to shock settings and roll centers to reach a balanced on-track setup.

Use this upper deck when you need a controlled increase in chassis stiffness for competitive T4 setups, testing incremental handling changes on track to find the best balance for your driving style.
