XRAY X4 Front Narrow Split Upper Deck Upgrade Graphite 2.0 - Factory Pro O-XCP015  [FP-O-XCP015]

Concise intro to the narrow split front deck

This Factory Pro option part is a narrow split upper deck front developed for the XRAY X4 chassis and supplied as an RC-scale graphite 2.0 replacement. It is intended to change front-end stiffness and the distribution of rigidity across the chassis top, allowing setup experimentation without altering the stock lower plate.

The deck fits using the X4's existing mounting points and is supplied as a direct swap for the original front upper deck. When fitting, check for clearance with the servo and suspension linkages, tighten fasteners in stages and confirm wheel toe and steering geometry after final tightening.

Tuning role: narrowing the split of the upper deck shifts chassis flex ahead of the centreline and can influence initial turn-in and mid-corner stability. Fit this graphite plate when you need a measurable change in front response, then evaluate effects via lap times and tyre wear to determine net benefit.
