Enhance your RC drivetrain with the XRay XR930230 Ceramic Ball set. These premium 3.175mm Si3N4 ceramic differential balls are designed to reduce friction and vibration, support higher RPM, and deliver a notable increase in differential lifespan.

Key Features

  • Set of 12 premium-quality ceramic balls (3.175mm diameter)
  • Extra-hard Si3N4 ceramic construction
  • Significant improvement of differential lifespan
  • Reduces friction and vibration for smoother operation
  • Higher RPM capabilities with stable performance
  • Very high durability when properly lubricated, aided by reduced slip and heat
  • Approximately 60% lighter than steel for lower rotating mass
  • 3–5 times longer lifespan than steel diff balls under matching conditions
  • Vastly superior corrosion resistance compared to steel
  • Low-friction coefficient and smooth surface finish

Ideal for maintaining a consistent, efficient differential, this XRay ceramic set focuses on longevity and smoothness without adding weight. Part number XR930230 ensures you are selecting the correct 3.175mm ceramic balls from XRay’s precision range.

• Set of 12 premium-quality ceramic balls
• Extra-hard Si3N4 silicone nitride ceramic
• Significant improvement of differential lifespan
• Reduces friction & vibration
• Higher RPM capabilities


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.
