Xray X4'26 Centre Top Deck Graphite 1.6 Medium - Factory Pro FP-O-XCP031S  [FP-O-XCP031S]

Factory Pro FP-O-XCP031S 1.6mm graphite centre upper deck for Xray X4'26

Role of the upper deck in chassis tuning

The FP-O-XCP031S upper deck is produced as a direct replacement for the Xray X4'26 chassis. As a medium-stiff 1.6mm graphite plate it sits across the bulkhead zone and central stack to govern local flex and distribute loads through the centre of the chassis. This part affects how the front and rear modules link via the centre structure and is a focused method to alter chassis stiffness without changing main suspension parts.

Material choice and manufacturing notes

Graphite continues to be the preferred material for upper decks thanks to its stiffness-to-mass ratio. The FP-O-XCP031S employs 1.6mm graphite to provide a balance between rigidity and forgiving compliance. The deck geometry, such as cutouts, mounting bosses and reinforced edges, controls its interaction with shock towers and bulkheads. Expect a low-mass, serviceable component that resists permanent deformation during normal use.

Compatibility and intended models

Designed for the Xray X4'26, the FP-O-XCP031S matches factory mounting points and interfaces for that chassis generation. It replaces the standard upper deck and its effect is localised to the centre section. This makes it most relevant for tuners assessing chassis feel or for those restoring vehicles to an original-style specification.

Recommended users

The deck is aimed at builders who run Xray X4'26 cars or collectors preserving platform authenticity. It suits anyone seeking a simple hardware replacement or a subtle mid-chassis stiffness change without altering suspension geometry. The component is useful for maintenance, restoration and precise chassis adjustments.

The Factory Pro FP-O-XCP031S is a pragmatic mid-stiffness graphite upper deck option for Xray X4'26 owners who want a dependable replacement that adjusts centre stiffness without major platform changes.
