Factory Pro O-XCP032S Xray X4'26 1/10 electric touring car rear upper deck - Graphite 1.6  [FP-O-XCP032S]

Factory Pro FP-O-XCP032S Xray X4'26 rear upper deck - graphite 1.6 as a focused chassis element

The Factory Pro FP-O-XCP032S is a purpose-built rear upper deck for the Xray X4'26 platform, machined in graphite at a nominal 1.6mm thickness. It is presented as a direct-fit structural component intended to alter the chassis stiffness distribution and preserve alignment of suspension pick-up points under load. The piece sits where the stock upper deck controls torsion and tie-in of the rear bulkhead, making it a part hobbyists look to when refining the baseline geometry of an X4'26 touring car chassis.

Material choice and mechanical role

Graphite at 1.6mm thickness balances rigidity with some flex, offering a middle ground between thin carbon plates and heavier composites. In practical terms this translates to a clear contribution to longitudinal and lateral stiffness without introducing excessive brittleness in small impacts. The machining and hole pattern follow the X4'26 geometry so mounting accuracy is retained, which matters when repeatable alignment is required across rebuilds or part swaps.

Platform context and fitment

Designed specifically for the Xray X4'26 chassis, the FP-O-XCP032S replaces the factory rear upper deck and uses existing mounting points. As an aftermarket structural plate it addresses the area of the chassis that influences rear-end traction transition and roll center behavior by modifying the section that ties the rear bulkhead to center bracing.

Who benefits from this part

This component is most relevant to hobbyists and builders who maintain or restore Xray X4'26 touring cars and who want a documented, dimensionally accurate graphite option for the rear upper deck. It is appropriate for those focused on chassis consistency, repeatable assembly, or collectors who prefer higher-spec replacement parts that match the original geometry but with different material characteristics.

Practical notes on selection

Consider this part as a targeted structural element: its impact is specific to chassis stiffness distribution and part-to-part repeatability. It is not a universal upgrade for all handling issues, but rather a discrete option for adjusting how the rear section of an X4'26 responds under load while keeping the original mounting architecture intact.

As a focused aftermarket component, the Factory Pro FP-O-XCP032S provides a dimensionally accurate graphite rear upper deck for the Xray X4'26. Its role is structural and specific, making it a practical choice for builders and collectors wanting consistent chassis behavior and material variation.
