Sharpen XB8 Rear Response with Composite Uprights

The XRAY 353352 XB8 Composite Rear Upright is manufactured from high-grade composite to provide an excellent strength to weight ratio, giving racers a durable component that stays light while standing up to hard use on the track.

Tunable Geometry and Weight Options

This upright offers two lower roll center positions for fine tuning rear grip and balance, and it accepts brass weights mounted under the hubs so you can lower the center of gravity to improve traction and stability at higher speeds.

Direct Fit for XB8 Chassis Upgrades

Made specifically for the XB8 chassis, the XRAY 353352 rear upright installs cleanly and supports incremental weight adjustments, making it a straightforward upgrade for drivers chasing better balance and on-track consistency.
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 these uprights fit other XRAY models?

These uprights are designed for the XB8 chassis and are unlikely to fit other XRAY models without modifications or different mounting hardware.

How should I test optional weight placement?

Start with small increments of brass weight under one upright and compare handling changes. Increasing weight lowers the center and can reduce rear roll, but tune gradually and note lap time differences.

What routine checks are recommended?

Regularly inspect the composite for hairline cracks, ensure mounting screws remain torqued, and clean contact areas to prevent debris from affecting fit and function.
