X4F Aluminium Rear Bulkhead with Adjustable Flex - XRAY 302784  [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 simplify alignment at assembly and help maintain identical geometry between runs, cutting setup variance when you swap parts or rebuild a chassis.

The bulkhead employs a universal left-right layout so one part number serves both sides, reducing spares. Countersunk mounting holes are machined to accept a 1.5mm aluminium chassis plate profile and standard screws, which streamlines hardware choices and increases durability where the bulkhead mounts to the chassis.

The main function is to accept an adjustable rear bulkhead brace that alters rear flex and handling balance, letting a single chassis be tuned for varied track surfaces without changing front top decks. There are attachment points to secure the shock holder directly to the bulkhead so chassis flex and shock response can be tuned separately.

Made from Swiss 7075 T6 aluminium and finished in black anodize, the part emphasizes dimensional stability and wear resistance suitable for RC touring car competition use.
