Fine-Tune Your XB2 Rear Geometry

The XRAY 323356 Aluminum Multi Adjustable Rear Upright provides a solid upgrade path for XB2 owners seeking consistent rear-end behaviour. Crafted from Swiss 7075 T6, this part balances toughness with minimal mass so you can make reliable setup changes session after session.

Adjust Roll Centre to Improve Traction

By aligning the upper roll centre with the driveshaft joint axis, this upright lets you influence the rear traction curve. Racers can use the adjustable positions to alter weight transfer and stability, which is particularly useful on carpet surfaces.

Choose the Right Material for Your Track

The XRAY 323356 is available in several material options to suit different track conditions and driving preferences. Options like hard, graphite, aluminium, and aluminium low let you tailor stiffness and feedback without changing core suspension geometry.

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.

Will this upright fit older XB2 kits?

In most cases yes, provided the older kit uses the same rear upright mounting layout as current XB2 models. Check your chassis mounting points to confirm fitment.

Which material option gives the most rear grip?

Graphite and softer aluminium low variants tend to offer more compliance and feel, which can translate to increased rear bite on low-grip carpet tracks compared to harder materials.

Do I need special tools to install the XRAY 323356?

Installation uses standard hobby tools. A set of hex drivers, precision pliers and a torque-aware driver for aluminium hardware will make the job straightforward.

How should I adjust settings for first track test?

Begin with the stock roll centre setting, then change one position at a time and log lap times. Adjust shock damping and rear toe after roll centre changes to fine-tune balance.
