X4F Aluminium Rear Lower Bulkhead for Tuning - XRAY 302784  [XR-302784]

The XRAY 302784 rear lower bulkhead is an RC component intended to centralize assembly and keep suspension geometry repeatable through maintenance and setup changes. Built-in centering pins assist accurate installation and help ensure the same geometry is restored after rebuilds.

One part number fits both left and right positions due to the universal design, reducing the number of spare parts required. Countersunk mounting holes are machined to accept a 1.5mm aluminium chassis plate profile and standard screws, which simplifies hardware selection and improves the longevity of the chassis connection.

Its chief role is to receive an adjustable rear bulkhead brace that modifies rear flex and handling bias, so a single chassis can be tuned for different track conditions without replacing front top decks. The bulkhead also provides attachment points for the shock holder, allowing chassis flex and shock response to be adjusted independently.

Machined from Swiss 7075 T6 aluminium and finished in black anodize, the part focuses on dimensional stability and wear resistance suitable for touring car applications.
