Pair of 12 premium-quality ceramic balls made out of extra-hard Si3N4 silicone nitride ceramic. Significantly improves differential lifespan while reducing friction and vibration. Greater RPM abilities.
High-speed ceramic diff balls have quite high durability (whenever properly lubricated) considering reduced slide along with heat. With ceramic being about 60percent lighter than metal, ceramic diff balls have actually a significantly paid off rotating mass. Together meaning the lifespan of ceramic diff balls is 3-5 times a lot longer than in comparison to steel diff balls under matching conditions. Ceramic diff balls have 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 paid down.
