Pair of 12 premium-quality ceramic balls made from extra-hard Si3N4 silicone nitride ceramic. Considerably improves differential lifespan while reducing friction and vibration. Greater RPM abilities.
High-speed ceramic diff balls have very high durability (whenever properly lubricated) considering reduced slip and heat. With ceramic being more or less 60percent lighter than steel, ceramic diff balls have a significantly lower rotating mass. Together which means the lifespan of ceramic diff balls is 3-5 times longer than compared to metal diff balls under matching conditions. Ceramic diff balls have vastly-superior corrosion opposition over steel diff balls, along with an inherent low-friction coefficient and smooth surface, frictional forces on ceramic diff balls are reduced.
