The XRAY Ceramic Ball 2.4mm (12) set, part number XR930220, provides a premium upgrade for ball differentials. Each 2.4mm ball is manufactured from extra-hard silicon nitride (Si3N4) ceramic. Compared with steel, these high-speed ceramic diff balls are approximately 60% lighter, reducing rotating mass to help the differential run smoother at higher RPM with less friction and vibration. When properly lubricated, durability is significantly increased, with a typical lifespan 3–5 times longer than steel under matching conditions. Their inherently low friction coefficient, smooth surface and excellent corrosion resistance further enhance consistency and longevity.

Set of 12 premium-quality ceramic balls made from extra-hard Si3N4 silicone nitride ceramic. Significantly improves differential lifespan while reducing friction and vibration. Higher RPM capabilities.

High-speed ceramic diff balls have very high durability (when properly lubricated) due to reduced slip and heat. With ceramic being approximately 60% lighter than steel, ceramic diff balls have a significantly lower rotating mass. Together this means that the lifespan of ceramic diff balls is 3-5 times longer than that of steel diff balls under matching conditions. Ceramic diff balls have vastly-superior corrosion resistance over steel diff balls, and with an inherent low-friction coefficient and smooth surface, frictional forces on ceramic diff balls are much lower.
