Precision Composite Upright to Improve Cornering

The XRAY 303363 Composite Left Rear Upright is built to sharpen handling in RC touring cars. It incorporates a 1 degree outboard toe-in to help the rear hold its line through corners, and its hard composite rigidity suits foam-tire competition while remaining usable with rubber tyres.

Designed for Race Setup and Tuning

This upright accepts compact 5x10 ball bearings to help lower unsprung mass and improve steering feel. The two roll center options let racers tweak rear geometry for different track conditions and driving styles.

Fitment Notes and Pairing

For balanced behaviour, fit the XRAY 303363 alongside the matching right rear upright, model 303353. Together they provide symmetric toe and roll center characteristics preferred by many competitive drivers.
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.

Can I run this upright on rubber tyres?

Yes. While the XRAY 303363 is tailored for foam-tire setups, its rigid composite construction also works with rubber tyres without altering the part's fitment.

Why choose a hard rigidity upright?

A stiffer upright reduces flex under load, keeping suspension geometry more consistent during high speed cornering typical in foam-tire racing.

Which bearings should I use and how should I install them?

Use quality 5x10 ball bearings and press them squarely into the hubs. Light lubrication on the seals helps break-in while avoiding excess oil that could attract dirt.
