Precision upright for sharper cornering

For serious hobbyists after finer handling, the XRAY 303361 Composite Left Rear Upright delivers a factory-set 1° outboard toe-in that helps stabilise suspension geometry during heavy impacts. The design aims to keep the rear end tracking true through fast turns and off-camber sections.

Designed for rubber tire setups

This upright uses medium rigidity marked "M", making it well suited to rubber-tire competition. It offers two selectable roll centre positions on the top mount and accepts compact 5x10 ball bearings to reduce unsprung mass and improve steering response.

Compatibility and practical use

The part pairs with the matching right rear upright 303351 and works with both rubber and foam tyre options, allowing straightforward setup changes for different track surfaces and grip levels.
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 this upright be used with foam tyres?

Yes. The XRAY 303361 supports both rubber and foam tyre configurations, so you can switch compounds without changing the upright.

What bearings fit this upright?

It is sized for small 5x10 ball bearings, which help keep rotating mass low and maintain crisp handling at the rear.

How do the roll centre options affect handling?

The two top roll centre positions let you trade rear grip versus turn-in behaviour; raising the roll centre typically reduces body roll, while lowering it can add rear traction on lower-grip surfaces.
