Xray X4'26 Chassis Upper Plate Graphite Medium - Factory Pro O-XCP031  [FP-O-XCP031]

Factory Pro FP-O-XCP031 Xray X4'26 Upper Deck Medium - Graphite 2.0: concise technical summary

The FP-O-XCP031 from Factory Pro is a direct-replacement graphite upper deck for the Xray X4'26 touring chassis. Its main structural duty is to connect bulkheads and set spanwise rigidity, which in turn shapes how the centre responds to driver inputs. The Graphite 2.0 iteration targets a medium stiffness that aims to balance torsional control with usable feedback.

Fitment and design goals

This plate uses the X4'26 OEM upper deck mounting pattern so no drilling or relocation of fasteners is required. The graphite construction cuts down on local flex relative to stock composite decks, and the medium thickness is chosen to sit between softer and firmer factory options, producing a stable centre without making the chassis overly stiff fore to aft.

Production and material specifics

Graphite 2.0 identifies an updated fibre layup and surface finish over prior versions. Expect precise thickness tolerances and a machined appearance that aids consistent stack heights. The medium stiffness rating is a compromise between torsional rigidity and retaining suspension feel.

Intended users and applications

This upper deck suits hobbyists who run an Xray X4'26 and want a like-for-like replacement or a material upgrade to adjust mid-range stiffness. It is suitable for tuners focused on repeatable chassis behaviour and collectors wanting a clearly versioned upgrade.

FP-O-XCP031 Graphite 2.0 provides a medium-stiff option for Xray X4'26 owners looking for reliable centre-section characteristics and an exact-fit replacement part.
