This XRAY 301093 upper deck is a purpose-built RC accessory for the X4F platform, supplied as a split-front carbon top deck with a nominal 2.0mm thickness. Its form is intended to let tuners alter front-end bite and steering response while keeping the basic suspension geometry unchanged.
The component is CNC-machined from high-grade carbon fiber as specified by the supplier, producing uniform stiffness and predictable flex characteristics across parts. The split-front layout shifts local flex ahead of the chassis centre, creating an extra tuning lever for track-to-track variation.
Fitting is straightforward for builders experienced with X4 series assemblies: the deck replaces the factory top deck using existing mounting points. Check fastener lengths and top-deck clearance to bodywork and electronics before final tightening, and confirm chassis symmetry after installation to maintain predictable steering behavior.
Use this split-front upper deck as a targeted tuning part to refine front-end bite and steering precision on X4F 2027 chassis layouts, integrating it with existing suspension and anti-roll settings rather than treating it as a single cure-all.
