Rear Upright Designed for Chassis Balance

The XRAY 323353-M Composite Rear Upright is produced from medium-hardness composite to achieve a reliable compromise between rigidity and measured give. It is produced for both sides of the car and includes seven upper roll centre positions so you can fine-tune rear behaviour.

Features That Preserve Geometry

With a 0 degree toe specification this upright helps keep suspension alignment steady under extreme loads, and the provision for a set-screw secures the pivot pin to avoid unwanted movement during competition.

Where This Upright Excels

Ideal for very-low to low-traction venues, the medium composite helps moderate grip and feedback. The layout uses larger 5x12mm bearings at the outer location to handle lateral forces while smaller 5x10mm bearings at the inner location trim rotating mass for more responsive suspension action.
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.

Is this part compatible with standard 1/10 touring cars?

The XRAY 323353-M is designed for many 1/10 scale touring and racing cars that share common rear hub geometry. Verify fitment dimensions and bearing sizes for your chassis before purchase.

What benefits do the seven roll centre positions give?

Multiple roll centre options allow you to alter weight transfer and roll behaviour. Higher positions can reduce roll and quicken turn-in while lower positions tend to increase traction and rotation on loose surfaces.

Can I use different bearing sizes if needed?

The component is engineered for 5x12mm bearings at the outer hub and 5x10mm at the inner hub to balance load capacity with low unsprung weight. Deviating from these sizes may affect fit and handling.

Any setup tips for low-traction tracks?

Start with a mid roll centre and small adjustments from there, pair the upright with compliant rear springs and test tyre pressures to find grip without inducing snap oversteer. Record each change to build a reliable baseline.
