Track-Focused Ceramic Differential Balls

RC racers seeking smoother on-road diffs will appreciate the Yokomo ZD-505CDA 3/32 inch ceramic differential balls. Made for SD and BD family differentials, these ceramic balls aim to maintain repeatable performance under race conditions.

Why Ceramic Helps on Tarmac

Ceramic balls are lighter and more wear-resistant than standard steel, which reduces rolling friction and keeps the diff operating smoothly over long runs. That means fewer mid-race changes and more consistent lap times.

Designed for 3/32 Inch Applications

The Yokomo ZD-505CDA size matches common on-road differentials that specify 3/32 inch balls, and the precision surface improves contact across the race for more linear diff behaviour.
Remark :
Due to limited stock availability, please notice that some Yokomo 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 alter my diff feel significantly?

You may notice a smoother, more consistent engagement. The change is subtle but favours predictable torque transfer on corner exit.

Are ceramic balls more brittle than steel?

Ceramics can be harder but less ductile than steel. They perform well under normal on-road loads but can be more susceptible to impact damage if overloaded.

How often should I inspect them?

Check balls and races whenever you rebuild the diff or after any heavy run. Look for surface chips or flat spots and replace if wear is evident.

Do they need a different diff oil?

No special oil is needed; stick to the diff oil you prefer. Lighter oils will give quicker action while heavier oils slow response.
