This XRAY 301093 upper deck is a dedicated RC-scale accessory for the X4F platform, supplied as a split front carbon top deck with a 2.0mm nominal thickness. Its geometry concentrates on a balance between traction and steering response, allowing chassis setup adjustments to influence handling without changing basic suspension geometry.
The part is CNC-machined from high-grade carbon fiber material sourced and produced as stated by the supplier, providing consistent stiffness and repeatable flex characteristics across samples. The split front layout modifies the local flex pattern ahead of the chassis center, offering an additional tuning axis for track-to-track variation.
Installation is straightforward for users familiar with X4 series assemblies, replacing the factory top deck and using existing mounting points. Check fastener lengths and top-deck clearance to body and electronics before final tightening, and validate chassis symmetry after installation to preserve predictable steering behaviour.
Use this split front upper deck as a tuning component to fine-tune front-end bite and steering precision on X4F 2027 chassis layouts, pairing it with established suspension and anti-roll settings rather than as a standalone change.
