Half the weight of tungsten carbide and almost twice as hard as steel, HCCA ultralite Diff Balls will decrease rotational mass for unprecedented acceleration and speeds. Very smooth, very hard, and very high wear resistance. In fact, our HCAA balls are much smoother, harder, and longer lasting than the standard steel balls included in car kits' ball differentials.
Compared to even the hardest of steel balls, our balls have: 114% greater tensile strength 107% greater yield strength 102% greater Modulus of Elasticity 102% greater density Every set is matched for consistent concentricity and quality control checked. All balls are Grade 10 (not the lower Grade 25 that some others use). For use with a wide variety of applications including in ball bearings, bicycles, valve balls and linear devices. AVAILABLE FOR VIRTUALLY EVERY POPULAR RC KIT!
