Sharper cornering with the XRAY 303351 upright

The XRAY 303351 Composite Right Rear Upright is a precision component built to boost on-track performance. It provides 1 degree of outboard toe-in to help your car hold the line through turns while preserving suspension geometry during heavy use or impacts. The medium rigidity is tuned for rubber-tire applications to deliver predictable handling and stability in race conditions.

Tuning and performance highlights

This upright offers two roll center positions so racers can dial in handling to match track traction and driving style. It uses compact 5x10 ball bearings to keep unsprung weight low, improving steering response and turn-in. The design remains versatile for both rubber and foam tire setups, giving you reliable feedback across surfaces.

Fitment and setup advice

Engineered to pair with the corresponding left-side rear upright (303361), this right-side piece helps maintain balanced geometry. For best results, match it with recommended rear components and adjust your toe, camber and roll center to suit your chosen tire type, whether you run rubber or foam tires.
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 upright work with foam tires?

Yes. The XRAY 303351 is compatible with both rubber and foam tires, though its medium rigidity is especially tuned for rubber-tire setups.

Which bearing size is required?

This upright accepts small 5x10 ball bearings to help minimise unsprung mass and sharpen response.

How do the two roll center positions change handling?

Using the higher roll center reduces body roll and gives a quicker initial reaction, while the lower setting improves traction and cornering balance. Test both to find the best compromise for your track.
