Performance and Tuning Benefits

The XRAY 353015 left rear bulkhead is designed to stiffen the rear structure on GT flat chassis layouts, delivering more consistent flex characteristics for predictable handling. It supports drivetrain alignment and helps maintain suspension geometry during hard acceleration and cornering, while permitting direct differential access for quick setup work.

Manufactured by CNC from Swiss 7075 T6 aluminium, the part features reinforced chamfers at load points and a smooth finish that resists wear. The split bulkhead arrangement separates maintenance access from the primary structural element, enabling differential service without disturbing the entire rear assembly.

Replacing softer composite bulkheads with this aluminium unit typically reduces rear compliance, improving throttle response and repeatability out of corners. Drivers who focus on diff preload, shock positions, or anti-squat adjustments will notice steadier behaviour lap after lap.

This left-side aluminium rear bulkhead is aimed at competitors and setup-focused builders wanting less chassis give at the rear and simpler diff servicing.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How does this bulkhead influence diff preload tuning?

By stiffening the rear structure, the bulkhead helps keep diff preload settings stable under load, which makes small preload changes more predictable and repeatable during setup sessions.

Will ride height or shock tuning need to change after installation?

You may need to revisit shock positions and spring rates because reduced rear flex alters the chassis response; start with minor adjustments and evaluate on-track balance before changing baseline settings.

Is the bulkhead compatible with different GT flat sub-variants?

It is intended for GT flat chassis configurations and GTX 2026 fits; confirm your chassis mounting points and geometries to ensure direct compatibility with specific sub-variants.

Does the aluminium unit change traction characteristics?

Reducing chassis flex often shifts traction behaviour, making throttle responses firmer and improving predictability. Track testing will show whether additional suspension or diff changes are needed to regain balance.

Any special tips for installing the split assembly?

Assemble the split sections loosely to check alignment, then progressively tighten bolts to specified torque to avoid introducing preload or misalignment between halves.
