Upgrade Your X1 with Precision 4.9mm Balls

The XRAY 373245 X1 Upper Arm Ball Universal, at 4.9mm, is made to improve handling and part life on the X1 series. Fabricated from HUDY Spring Steel, these balls deliver consistent geometry and resistance to wear under load.

HUDY Spring Steel for Strength and Finish

HUDY Spring Steel is chosen for its high fatigue resistance and excellent surface finish. Each ball is CNC machined to tight tolerances to reduce play and lower friction where it matters.

Fitment and Tuning Use Cases

This pair of upper arm balls is manufactured for the XRAY X1 series to ensure correct fit and predictable behaviour. Use them when rebuilding suspension or fine tuning handling for race or club runs.

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.

Are these balls compatible with other XRAY models?

They are engineered for the XRAY X1 series so direct fitment to other models is not guaranteed; some models may require adaptors or modification to use them.

What does HUDY Spring Steel give me on track?

HUDY Spring Steel provides improved wear resistance and a smooth machined surface which helps reduce friction and maintain stable suspension action lap after lap.

How many balls come in the set and where do they fit?
