XRAY 302784 - X4F Aluminium Rear Bulkhead, Adjustable Flex, Swiss 7075 T6  [XR-302784]

This XRAY 302784 rear lower bulkhead is an RC-scale component designed to centralize assembly and keep suspension geometry repeatable during setup changes. Centering pins on the part ease alignment at assembly and help preserve the same geometry between runs, reducing setup variability when you swap parts or rebuild a chassis.

The bulkhead uses a universal left-right design so a single part number covers both sides, lowering your spares count. Countersunk mounting holes are machined to accept a 1.5mm aluminium chassis plate profile and standard screws, which simplifies hardware choices and improves long-term durability where the bulkhead fastens to the chassis.

Its primary purpose is to accept an adjustable rear bulkhead brace that changes rear flex and handling balance, allowing one chassis to be tuned for different track conditions without multiple front top decks. Attachment points are provided to secure the shock holder directly to the bulkhead so chassis flex and shock response can be tuned independently.

Manufactured from Swiss 7075 T6 aluminium and finished in black anodize, the part focuses on dimensional stability and wear resistance appropriate for RC touring car use.
