Rear Upright Focused on Tunability

The XRAY 323353-M Composite Rear Upright uses a medium-hardness composite to deliver a useful mix of resilience and controlled flex. It fits both left and right sides and offers seven upper roll centre positions so you can refine rear-end behaviour for different track types.

Engineering for Stability

Configured with 0 degrees of toe, this upright helps maintain rear geometry under load, and the set-screw provision locks the pivot pin in position to prevent shift during intense running.

Surface Performance and Bearing Layout

Matched to very-low through low-traction conditions, the medium compound gives predictable traction without being overly stiff. The larger 5x12mm bearings in the outer hub cope with higher dynamic loads while the inner 5x10mm bearings reduce unsprung mass for crisper handling.
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 improve rotation on low-grip tracks?

Fitted in the right roll centre position, the XRAY 323353-M can help the rear rotate more predictably on low-grip surfaces, giving you better corner exit control. Try small changes to find the sweet spot.

Is the 0 degree toe adjustable on this part?

The upright itself is manufactured with 0 degree toe. Toe adjustments are usually achieved elsewhere in the rear suspension layout, so check your hub carriers and links for tuning options.

How do I maintain these uprights after racing?

Inspect for play at the pivot pin and bearings, clean bearings regularly and replace if worn, and confirm the set-screw remains tight after a few runs to keep consistent performance.
