Left rear bulkhead - GT flat chassis upgrade XRAY 353015  [XR-353015]

Rear Bulkhead: Installation and Compatibility Notes

The XRAY 353015 left rear bulkhead is intended for GT flat chassis arrangements where improved rear stiffness and predictable flex are required. It maintains drivetrain alignment and keeps suspension geometry stable under load, while offering direct differential access for servicing and quick setup changes.

Fabricated from Swiss 7075 T6 aluminium via precision CNC machining, the component delivers a rigid structure with strengthened chamfers on key load-bearing features and a high-quality finish. The split bulkhead design separates the service interface from the main structural plate, so diff removal and inspection can be completed without stripping the complete rear assembly.

Fitting this aluminium piece in place of a composite bulkhead reduces unwanted compliance at the rear, often resulting in firmer throttle feedback and more consistent corner exits on GT flat chassis platforms. Those who adjust diff preload, shock mounting positions, or anti-squat will benefit from the bulkhead's ability to hold settings run after run.

This left-side aluminium rear bulkhead targets road-race competitors and tuners who need lower chassis compliance and easier access to the differential without complex fitment work.
