Xray X4'26 Upper Deck Graphite 2.0 Medium Stiffness - Factory Pro O-XCP031  [FP-O-XCP031]

Factory Pro FP-O-XCP031 Xray X4'26 Upper Deck Medium - Graphite 2.0: practical breakdown

The Factory Pro FP-O-XCP031 is a direct-fit graphite upper deck engineered for the Xray X4'26 touring chassis. The upper deck acts as a structural panel linking the front and rear bulkheads, determining spanwise rigidity and influencing centre response to driver inputs. This Graphite 2.0 medium variant is tuned to improve mid-range torsional balance while keeping useful compliance.

Integration and intended behaviour

The plate installs into the X4'26 upper deck locations and follows OEM mounting patterns so no modification is necessary. Compared with standard composite decks, graphite decreases localized flex, and the medium thickness sits between low and high stiffness factory options to deliver a stable but not overly rigid chassis centre.

Manufacture and material comments

Graphite 2.0 denotes an improved layup and finish over earlier releases, producing a neat machined surface and consistent thickness tolerances to help preserve stack heights. The medium stiffness aims to cut unwanted chassis twist without fully damping mechanical feedback from the suspension.

Use cases and audience

This upper deck is intended for hobbyists who keep an Xray X4'26 platform and want a reliable replacement or an upgrade that subtly alters mid-range stiffness. It is useful for racers seeking repeatable handling and collectors who value versioned material upgrades.

FP-O-XCP031 Graphite 2.0 gives Xray X4'26 owners a measured medium stiffness alternative for consistent chassis reactions and a simple, direct-fit replacement.
