Xray Premium-quality ceramic balls

Xray have released a set of 12 premium-quality ceramic balls made from extra-hard Si3N4 silicone nitride ceramic. Available in 2.4mm and 3.175mm they significantly improve differential lifespan while reducing friction and vibration. High-speed ceramic diff balls have very high durability, when properly lubricated, due to reduced slip and heat and with ceramic being approximately 60% lighter than steel, ceramic diff balls have a significantly lower rotating mass.
