Precision Carbide Balls for Consistent Diff Performance

For club racers and hobbyists seeking durable components, XRAY 930130 3.175mm carbide balls preserve roundness and promote consistent differential behaviour compared with conventional steel balls.

Benefits of Carbide Versus Steel

The increased hardness of carbide minimises surface fatigue and deformation, which helps maintain smooth engagement and reduces the frequency of diff servicing on busy race days.

Full 12 Ball Set for Complete Replacement

This pack contains 12 carbide balls, enough for a complete ball differential refresh. Replacing all balls at once helps keep diff characteristics uniform and dependable during competitive running.
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 these improve lap consistency?

They can contribute to more consistent lap times by keeping diff behaviour predictable, especially as carbide resists wear that would otherwise change diff feel over a race program.

Do I need to change diff rings or cones when fitting carbide?

Inspect rings and cones; if they show wear, replace them too. Carried-over worn components may limit the benefits of the new carbide balls.

Are these balls suitable for both on and off road models?

Yes, carbide balls suit a wide range of models and surfaces, from smooth indoor tracks to outdoor layouts where increased durability helps performance under varied conditions.

How should I set preload after installing these balls?

Set preload according to your diff manual and then fine tune by feel. Because carbide changes wear characteristics, small preload adjustments may be needed to match your driving style.
