Couple of 12 premium-quality ceramic balls made out of extra-hard Si3N4 silicone nitride ceramic. Notably improves differential lifespan while reducing friction and vibration. Better RPM abilities.
High-speed ceramic diff balls have quite high durability (whenever properly lubricated) considering reduced fall along side heat. With ceramic being about 60percent lighter than steel, ceramic diff balls have actually a significantly paid down rotating mass. Together meaning the lifespan of ceramic diff balls is 3-5 times considerably longer compared to comparison to metal diff balls under matching conditions. Ceramic diff balls have actually really vastly-superior corrosion opposition over steel diff balls, with an inherent low-friction coefficient and smooth area, frictional forces on ceramic diff balls are reduced.
