Set of 12 premium-quality ceramic balls made from extra-hard Si3N4 silicone nitride ceramic. Dramatically improves differential lifespan while reducing friction and vibration. Higher RPM abilities.
High-speed ceramic diff balls have very high durability (whenever properly lubricated) considering paid off slide as well as heat. With ceramic being about 60percent lighter than metal, 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 steel diff balls under matching conditions. Ceramic diff balls have vastly-superior corrosion opposition over steel diff balls, with an inherent low-friction coefficient and smooth surface, frictional forces on ceramic diff balls are lower.
