XRAY X4F'25 Upper Deck Rear Graphite 2.0 by Factory Pro O-XCP023  [FP-O-XCP023]

Upper deck rear for X4F'25

This Factory Pro replacement is an RC-scale upper deck rear designed specifically for the XRAY X4F'25 chassis and finished in a graphite 2.0 construction. It serves as a direct chassis component to influence rear section stiffness and balance without implying any full-size vehicle use.

As a tuning part, the graphite 2.0 plate changes how the rear of the chassis responds to weight transfer and cornering forces; swapping this deck is commonly used to reduce rear flex and stabilise traction on medium- to high-grip asphalt tracks. Fitment focuses on alignment with existing bulkheads and screw points, so confirm seat alignment and clearance with suspension and drivetrain before final torqueing.

Installation notes: remove the original deck, retain or replace factory fasteners as needed, check screw engagement depth to avoid contact with suspension components, and tighten progressively to even torque to preserve chassis flatness. After fitting, verify wheel toe and droop to ensure no binding was introduced during assembly.
