4.9mm Upper Arm Balls Built for X1 Performance

The XRAY 373245 X1 Upper Arm Ball Universal, 4.9mm in diameter, is produced to support precise suspension articulation on the X1 series. HUDY Spring Steel construction gives these balls high resistance to wear under heavy use.

Why HUDY Spring Steel Works Well

HUDY Spring Steel is valued for consistent mechanical properties and a fine surface finish. Precision CNC work ensures uniform size and roundness, which helps maintain reliable steering and suspension geometry.

Practical Use and Compatibility

Provided as a two-item set tailored for the XRAY X1 series, these upper arm balls are suitable for racers and club drivers replacing worn parts or experimenting with setup changes.
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 use these on non-X1 vehicles?

They are sized for X1 series fitment; while they may fit other cars with similar pivot dimensions, confirm the 4.9mm size and mounting layout first.

How do these affect setup changes?

Using precise, low-friction balls can make suspension behavior more consistent, which helps when adjusting camber, toe or roll centre for tuning purposes.

What maintenance do they need?

Regular inspection for wear and keeping pivots clean and lightly lubricated will prolong service life; replace the balls when signs of rounding or scoring appear.
