The XRAY 301093 upper deck is an RC-scale upgrade for the X4F platform, supplied as a split-front carbon top deck with a 2.0mm nominal thickness. Its geometry aims to balance front traction and steering response while leaving core suspension geometry intact.
CNC-machined from high-grade carbon fiber as described by the supplier, the deck offers repeatable stiffness and consistent flex characteristics across units. The split at the front modifies local flex ahead of the chassis centre, providing an additional tuning variable for different track conditions.
Installation typically replaces the factory top deck using the existing mounting points. Before final tightening, check fastener lengths, ensure clearance with the body and electronics, and verify that the chassis remains symmetrical to avoid steering bias.
Fit this split-front upper deck as part of a considered setup plan to refine front-end bite and steering precision, working alongside your current suspension and anti-roll settings for best results.
