Balanced Rear Uprght for Predictable Handling

The XRAY 323353-M Composite Rear Upright is moulded from a medium-hardness composite to deliver a practical blend of strength and controlled flex. It is produced for both left and right fitment and features seven upper roll center positions so you can dial in handling balance for different track conditions.

Stability-Focused Design Details

Set up with a 0° rear toe this upright helps keep suspension geometry stable under load, and a dedicated hole for a set-screw secures the pivot pin to reduce slop during aggressive cornering.

Track Suitability and Bearing Layout

Targeted at very-low to low-traction surfaces, the medium composite compound provides dependable control and feedback. The outer hub accepts larger 5x12mm bearings to cope with dynamic forces while inner 5x10mm bearings cut unsprung weight for sharper response.
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.

Which cars will accept this rear upright?

The XRAY 323353-M suits a wide range of 1/10 scale RC cars that use similar rear hub geometry, particularly setups that need added stability on low-traction surfaces. Check your hub dimensions before fitting.

How do I pick the roll center slot?

Try higher roll centre positions for reduced body roll and quicker turn-in on grippy layouts, and lower positions to increase traction and rotation on slide-prone, low-traction tracks. Tune by small increments.

Can I change the bearings in the hub?

The design uses 5x12mm bearings at the outer hub and 5x10mm at the inner location. Using the specified sizes preserves strength and keeps unsprung mass low for better handling.
